A useful collection record should do more than repeat a product name. It should identify the physical plaque in front of you, distinguish verified product facts from your own observations, connect the plaque to its accompanying documentation and preserve a visual baseline for later condition checks.
For the Moscow Metro Slate Edition, that means recording the individual edition number, natural slate characteristics, approximate format, artwork description, Certificate of Authenticity and independent status without assigning an unsupported train model, route or operator connection. The following workflow is intended for private collectors, studio archives and transit-art collections cataloguing a specific example from the 25-piece edition.
What a Complete Collection Record Should Establish
A strong catalogue entry answers five basic questions: what is the object, who created it, which example is it, what accompanied it and what was its condition when recorded?
For this edition, the core record should establish:
- The verified product title and creator
- The collection or series context
- The object type, material and production method
- The approximate dimensions and landscape orientation
- The edition size and the individual number shown on the reverse
- The presence and condition of the Certificate of Authenticity
- The plaque’s natural edge, surface, stone-tone and engraving characteristics
- A neutral description of the full side-view train artwork
- The artwork’s independent and unaffiliated status
- Which items entered the collection with the plaque
- The object’s condition, storage or display location and inspection date
Keep three kinds of information separate. Verified product facts come from the maker’s listing or supplied documentation. Object-level observations come from inspecting your individual plaque. Collection-management information includes your accession number, acquisition date, location and photograph references.
This separation prevents common archival errors. An approximate published size should not be presented as a precision measurement of the individual object. A natural mark visible on one plaque should not be attributed to the entire edition. A collector-assigned accession number should not be confused with the artwork’s edition number.
Use the Verified Title, Creator and City Series Context
Enter the title as Moscow Metro Slate Art – Laser-Engraved Limited Edition. The creator or maker can be recorded as Chromatica, and the broader collection context as City Series & Subway Culture.
If your archive distinguishes between creator, designer, producer and publisher, do not guess at roles that are not stated in the available documentation. A concise entry such as “Chromatica; designed and laser-engraved in Germany” stays within the verified information.
The product type can be recorded as engraved slate artwork or slate art plaque. Avoid classifying it as an official transport sign, railway artefact, operational object or Moscow Metro-issued collectible. It is an independent urban-art object inspired by transit culture.
Useful source identifiers can also be retained:
- Product SKU: ET-ST-CS13
- Product family: City Series & Subway Culture
- Product source: CHROMATICA product listing for “Moscow Metro Slate Art – Laser-Engraved Limited Edition”
If you maintain a source-history field, include the date on which you consulted the product listing. Web pages can change, so an access date helps explain which information was available when the record was made. A saved screenshot or PDF may also be useful for a private archive, provided it is clearly labelled as a captured reference rather than part of the edition.
Record the Edition Number Exactly as It Appears
The worldwide edition is limited to 25 pieces. Each plaque is numbered on the reverse from 01/25 to 25/25. For the object-level entry, transcribe the number exactly as it appears on your plaque, including its leading zero and slash.
For example, if the reverse reads “07/25,” enter:
- Edition statement: 07/25
- Edition size: 25
- Individual number: 07
- Number location: Reverse of plaque
Do not normalize “07/25” to “7 of 25” in the primary transcription field. You can add “number 7 from an edition of 25” in a plain-language note, but the exact inscription should remain preserved elsewhere in the record.
The edition number is not the same as your collection accession number. A collector or institution might assign an internal identifier such as “TA-2026-014,” but that code belongs to the archive. It should appear in a separate field and should not be written on the plaque or Certificate of Authenticity.
Photograph the reverse number clearly enough to read it without image enhancement. Take one wider reverse view to show where the number is positioned and one closer image for transcription. Retain the unedited original files. Cropped or adjusted copies can be useful for reference, but they should not replace the original intake photographs.
Do not infer current availability from the numbering range. The fact that the edition runs from 01/25 to 25/25 does not establish which numbers remain available, when a particular number was sold or the ownership history of any example.
Link the Plaque and Certificate of Authenticity
One plaque and a Certificate of Authenticity are included with the edition. In the catalogue, record the certificate as an accompanying document rather than treating it as a second artwork.
A practical documentation sequence is:
- Assign the plaque an internal accession or collection ID.
- Record the Certificate of Authenticity under the same ID as an associated document.
- Photograph the certificate separately, front and reverse where relevant.
- Transcribe only the information that is actually visible on the certificate.
- If the certificate displays an edition number or other object-specific identifier, compare it with the plaque and record whether the details correspond.
- If no matching number appears on the certificate, do not add one by assumption.
A simple relationship note might read: “Certificate of Authenticity received with plaque and retained as associated documentation under collection ID TA-2026-014.”
Record the certificate’s physical condition independently. Useful notes include whether it is present, whether it has folds, edge wear, marks or annotations, and where it is stored. Do not place adhesive collection labels over printed or handwritten information.
The Certificate of Authenticity documents the maker’s presentation of the work. It should not be described as proof of legal title, third-party authentication, operator approval or government endorsement. Likewise, the presence of a certificate does not by itself establish a complete ownership history. If acquisition invoices, correspondence or transfer records exist, catalogue them as separate provenance or transaction documents.
Document Material, Dimensions and Landscape Format
The verified material and format description is:
- Material: Natural black slate
- Image process: Light laser engraving
- Published dimensions: Approx. 30 × 20 cm
- Orientation: Landscape
- Edge character: Natural irregular broken edges
- Production detail: Designed and laser-engraved in Germany
Because the published dimensions are approximate and the edges are naturally irregular, avoid presenting 30 × 20 cm as an exact measurement of every plaque. In a detailed collection system, use separate fields for published dimensions and measured dimensions.
If you measure your individual example, state how the measurement was taken. Irregular edges can produce different results depending on the points selected. Record the maximum height and width if that is your normal method, and identify the unit. Do not create false precision by adding decimal places that your measuring process cannot reliably support.
Do not infer weight, thickness, mounting compatibility or framing requirements if those details have not been measured or independently verified. A catalogue entry is more reliable when an unknown field is left blank or marked “not recorded” than when it is completed by assumption.
Photograph Natural Edges, Stone Texture and Engraving Variation
Natural slate is not visually uniform. The surface, edge shape, stone tone and engraving brightness can vary from piece to piece. These characteristics help distinguish the individual object, but they need to be documented carefully so that natural variation is not automatically recorded as damage.
An effective intake photograph set includes:
- Full front: The entire plaque, photographed straight on.
- Full reverse: The complete back, including the location of the edition number.
- Edition-number detail: A readable close view of the reverse numbering.
- Four edge views: Top, bottom, left and right, showing the irregular outline.
- Corner or transition details: Areas where the broken edge profile changes noticeably.
- Surface details: Visible mineral variation, texture or marks that help identify the individual plaque.
- Engraving details: Representative close views of lighter and darker engraved areas.
- Certificate views: The associated Certificate of Authenticity photographed separately.
- Context view: The plaque and certificate together, without unrelated display props obscuring either item.
Use even, neutral lighting where possible. Strong side lighting can be useful for showing texture, but it can also exaggerate relief and make ordinary stone variation appear more severe. A balanced archive set can include one evenly lit identification image and additional angled-light photographs for surface detail.
Avoid relying only on product photography. The product listing represents the edition, while your intake images document the specific plaque in your collection. Natural edge shape, stone tone, surface texture and engraving brightness should not be expected to match another example exactly.
In written notes, use descriptive language rather than diagnostic language. “Light-toned mineral variation near lower edge” is more useful than “defect” unless you have evidence that the area is damage. Likewise, an irregular edge is part of the verified material character; a newly detached fragment or fresh impact mark would be a condition issue. The distinction depends on direct inspection and, ideally, comparison with earlier photographs.
Describe the Full Side-View Train Artwork Accurately
The central image is an original Chromatica interpretation of a Moscow Metro train shown in full side view. Its visual approach draws on technical carriage structure, urban rail culture and the atmosphere of deep underground infrastructure. The light engraving creates an archive-like contrast against the dark slate.
A suitable catalogue description is:
“Landscape-format natural black slate plaque with a light laser-engraved, full side-view interpretation of a Moscow Metro train. The image uses a technical transit-art aesthetic and is presented as an independent urban-art work.”
Keep the description at the level supported by the artwork and product documentation. Do not identify the train as a specific rolling-stock model unless that identification has been independently verified and its source recorded. Do not assign a route, line number, service period, station or operational context.
Descriptions such as “route-specific carriage,” “historic fleet type” or “official technical drawing” introduce claims that are not established by the verified information. Even if the image resembles a real train type, resemblance alone is not sufficient for an archival identification.
Record Its Independent and Unaffiliated Status
The artwork is an independent artistic interpretation. It contains no official operator logos, state emblems, route numbers or line identifiers and is not affiliated with any transport company.
This status belongs in the catalogue because the terms “Moscow Metro” and “transit art” can otherwise lead later readers to mistake the plaque for operator-issued merchandise or a reproduced operational document.
A concise rights or status note can state:
“Independent Chromatica artwork inspired by Moscow transit culture. Not affiliated with or presented as official merchandise of a transport operator or government body. The artwork does not contain official operator logos, state emblems, route numbers or line identifiers.”
Do not place the object in an “official railway memorabilia” category unless your collection system uses that heading broadly and provides a clear independent-art subcategory. Better classifications include “transit-inspired art,” “urban-art collectible,” “engraved slate artwork” or “independent subway-culture art.”
Separate Included Items from Stands, Frames and Other Props
The verified included items are:
- One engraved natural black slate plaque
- One Certificate of Authenticity
Display stands, frames and other photographed props are excluded unless a current listing explicitly states otherwise. If your plaque later enters a frame or is placed on a stand, record that accessory as collection equipment or a later display component, not as an original part of the edition.
This distinction matters when the object moves between displays, is loaned or changes ownership. A future reader should be able to tell what accompanied the work from the maker and what was added by the collector.
If additional packaging, receipts or correspondence were retained, they may still be valuable archive materials. List them under separate headings such as “packaging retained,” “acquisition document” or “collector-added accessory.” Do not silently fold them into the edition contents.
Create a Practical Condition and Location Record
A condition record should describe the object at a known point in time rather than making a general claim about durability. Complete the first inspection when the plaque enters the collection, before framing, customization or long-term display if possible.
Record:
- Date of inspection
- Name or initials of the person conducting the inspection
- Overall front condition
- Overall reverse condition
- Edge and corner observations
- Surface observations
- Engraving appearance
- Readability and condition of the edition number
- Presence and condition of the Certificate of Authenticity
- Any detached material or separate fragments, if present
- Photograph file references
- Current storage or display location
- Any collector-added stand, frame or mounting arrangement
Use stable location names such as “Studio archive, cabinet 2, shelf B” rather than temporary descriptions such as “on the desk.” Update the record whenever the plaque moves, enters a frame, goes on loan or receives a collector-authorized alteration.
The product is described as customizable with suitable acrylic paint or paint markers. If an individual plaque has been customized, document that intervention as a later alteration unless supplied records establish otherwise. Record the date, materials and person responsible when known, and preserve photographs from before and after the change. Do not describe an undocumented collector addition as part of the original engraved edition.
A condition note should remain factual. For example: “Irregular natural edge profile visible on all sides; light-toned surface variation at upper right; no detached fragments observed during intake inspection.” This is more useful than broad terms such as “perfect” or “mint,” which can conceal the natural characteristics of slate and are difficult to apply consistently.
