The Melbourne birch wood art board carries several details that serve different purposes. “Design 19” identifies the artwork within the Chromatica City Series, while a reverse marking such as 07/25 identifies one physical board within the Melbourne edition of 25 pieces. The supplied Certificate of Authenticity is supporting documentation for the board; it is not a replacement for reading and recording the details on the object itself.
Keeping those identifiers separate matters. A collector who records only “19” could be referring to the design, not the individual board. Someone who reads “07/25” as a production date or manufacturing sequence would be assigning information that the edition number does not establish. This guide explains what each detail means, what it does not mean and how to create an accurate collection record without making unsupported assumptions.
The Three Identifiers to Check on the Melbourne Board
When identifying this edition, check three connected but distinct elements:
- The artwork designation: Melbourne, presented as an independent interpretation of Melbourne train culture.
- The City Series design number: Design 19, also expressed in the product copy as “19 Melbourne.”
- The individual edition number: a reverse marking from 01/25 through 25/25.
These details work at different levels. “Melbourne” tells you which subject or city design you are looking at. “Design 19” places that artwork within the 25-design City Series platform. The fraction-style marking on the reverse identifies the individual physical board within the limited Melbourne birch wood edition.
| Detail | What it identifies | What it does not establish |
|---|---|---|
| Melbourne | The city and train-culture subject of the artwork | A specific operator, route, railway line or train model |
| Design 19 | The Melbourne design within the City Series | The individual board or its production date |
| 01/25–25/25 | One numbered board within the 25-piece Melbourne edition | Production order, sale order, engraving date or market value |
The material and format provide a further identity check: the verified product specification is a permanent laser engraving on 3 mm birch wood in A4 landscape format, approximately 29.7 × 21 cm. These are physical product details rather than edition identifiers, but they are useful when distinguishing this version from other objects or formats in a collection.
What “Design 19” Means Within the City Series
Design 19 refers to the Melbourne artwork’s place in the Chromatica City Series. The first City Series is a 25-design collector platform built around city, graffiti, train-culture and urban-art themes. Within that system, Melbourne is designated as number 19.
The key point is that a design number belongs to the artwork concept, not to one particular physical board. Every correctly identified board from this Melbourne birch wood edition shares the Design 19 designation. If two collectors own different numbered examples—such as 03/25 and 18/25—both still own Design 19.
It helps to think of the design number as a catalogue position. It answers:
Which City Series design is this?
The answer is:
Design 19: Melbourne.
The design number does not tell you when a particular board was engraved, purchased or delivered. It also should not be expanded into claims about release sequence without separate evidence. Although “19” identifies the design within a numbered set, it does not by itself prove that the Melbourne artwork was conceived, manufactured or released nineteenth in chronological order.
This distinction becomes especially useful when collecting more than one City Series design. A catalogue can use the design number to sort the different artworks while using the edition number to distinguish individual examples of the same artwork.
How to Read the Reverse 01/25–25/25 Edition Number
The Melbourne birch wood edition is limited to 25 pieces worldwide. Each board is individually numbered on the reverse from 01/25 to 25/25.
The notation has two parts:
- The number before the slash identifies the individual numbered board.
- The number after the slash states the total size of the edition.
For example, 07/25 means that the object is the board numbered 07 within an edition limited to 25 pieces. The denominator remains 25 throughout the edition; the numerator changes from one numbered board to the next.
The leading zero in 01, 02 or 07 is part of the presentation of the edition number. It does not create another category or change the size of the edition. Board 07/25 is the seventh numbered example in the notation used for this edition, and it remains one of 25 total pieces.
What the edition number does not tell you
An edition number is an identifier, but it should not be treated as a complete production history. Nothing in the verified product information establishes that the numerator records:
- the order in which the boards were engraved;
- the order in which they passed inspection;
- the order in which they were listed or sold;
- the date on which they were produced;
- the date on which they entered a collection; or
- their relative quality, rarity or value.
Accordingly, a board marked 01/25 should not automatically be described as “the first one made.” It is more accurate to call it the example numbered 01/25. Likewise, 25/25 means the board carries the final number in the edition’s numbering range, not necessarily that it was the last board engraved or sold.
Lower numbers are not verified as rarer or inherently more collectible than higher numbers. All numbers sit within the same stated worldwide edition of 25. Personal preference for a particular number is possible, but preference should not be confused with a documented difference in edition status.
Design Number Versus Edition Number: Why They Are Not the Same
Both identifiers use numbers, which is why they are easy to confuse. Their functions are different:
- Design 19 identifies the Melbourne artwork across the City Series.
- 07/25, for example, identifies one physical board within the limited Melbourne edition.
A useful test is to ask whether the number changes from board to board. The design number does not: every board in this edition carries the Melbourne Design 19 identity. The reverse edition number does change: each individually numbered board occupies one position between 01/25 and 25/25.
| Question | Relevant identifier |
|---|---|
| Which City Series artwork is this? | Design 19: Melbourne |
| Which numbered example do I have? | The reverse number, such as 07/25 |
| How many pieces are in the Melbourne edition? | The denominator 25 |
| When was my board produced? | Not established by either number |
| Which operator or train model is shown? | Not established by either number |
This separation is standard good practice when cataloguing limited art objects. One field identifies the work or design; another identifies the physical editioned example. Combining them into a single unexplained number makes a collection record harder to interpret later.
A clear short-form notation would be:
Chromatica City Series, Design 19 Melbourne, board 07/25.
That wording makes it immediately clear that 19 and 07/25 describe different parts of the object’s identity.
What the Certificate of Authenticity Adds
Each Melbourne birch wood art board is supplied with a Chromatica Certificate of Authenticity. The certificate belongs with the supporting documentation for the physical product and should be retained with the collection record.
The safest way to use the certificate is to record only the information that is actually printed on the certificate in your possession. The verified product information confirms that a certificate is included, but it does not establish that every certificate contains a particular combination of serial numbers, signatures, issue dates or security features.
Do not assume that the certificate repeats the reverse number unless you can see a matching number on the document. Similarly, do not add a signature, date or certificate reference to a catalogue entry unless that feature is physically present and legible.
For practical collection management, treat the certificate and the board as two related items:
- the board carries the physical artwork, material characteristics and reverse edition number;
- the certificate is the accompanying Chromatica documentation supplied with it.
Photographing or transcribing both separately avoids a common problem: retaining a general image of the artwork but losing the evidence needed to identify the individual numbered example. If the certificate is stored away from the board, the collection record should note its location without attaching unverified descriptive claims to it.
Which Physical Details Belong in a Collection Record
A useful record should be specific enough to identify the object without turning assumptions into facts. For the Melbourne edition, the core verified details are:
- Brand or maker: Chromatica
- Series: City Series
- Design: Design 19 Melbourne
- Object type: birch wood art board
- Material: 3 mm birch wood
- Process: permanent laser engraving
- Format: A4 landscape
- Approximate dimensions: 29.7 × 21 cm
- Edition size: 25 pieces worldwide
- Individual number: transcribe the reverse marking exactly
- Certificate: Chromatica Certificate of Authenticity supplied
The product reference ET-WD-CS19 can also be retained as a catalogue or purchase-reference field. It should not be described as an inscription on the board unless it is visibly present on the particular object being documented.
Record observation separately from interpretation
Good cataloguing distinguishes what can be directly observed from what has been inferred. For example:
- Observation: “Reverse marked 07/25.”
- Supported interpretation: “Numbered example 07 from a worldwide edition of 25.”
- Unsupported interpretation: “Seventh board produced.”
The same method applies to the artwork:
- Observation: “Laser-engraved Melbourne train artwork.”
- Supported interpretation: “Independent artistic interpretation of Melbourne train culture.”
- Unsupported interpretation: “Official depiction of a named operator’s train on a particular route.”
If the board has been customized with suitable acrylic markers, record that separately from the original product specification. Useful wording is “collector-customized with acrylic marker” followed by the date and artist or owner name, if known. This preserves the distinction between the permanent engraved base and later additions made by the collector.
Photographs can complement the written record. A practical set includes the full front, the full reverse, a clear close-up of the edition number and a separate image of the certificate. Images should document what is present rather than attempt to prove details that are not visible.
How Natural Birch Grain Can Affect the Engraved Appearance
The board is made from natural birch wood. Its grain, base color and surface texture can vary, producing subtle tonal differences in the engraved result. This means two boards from the same Melbourne edition may not look perfectly identical even though they share the same artwork, material specification and engraved design.
The engraved lines can appear darker or lighter in particular areas depending on the underlying wood. Grain direction and local tonal variation may also affect how the image reads under different lighting. These differences do not create separate designs or edition categories. Both objects remain Design 19, and each remains identified by its own reverse edition number.
Natural variation should be described carefully. It is reasonable to note visible differences in grain, base tone, surface texture or engraving tone. It is not necessary to claim that every board has a wholly unique grain pattern. The supported point is narrower: natural birch can show subtle variation from board to board.
When photographing the piece for a catalogue, neutral and even lighting generally makes the engraved linework and wood tone easier to compare. Record what the board looks like rather than trying to normalize every tonal difference through heavy image editing.
What the Melbourne Artwork Does—and Does Not—Identify
The artwork is framed as an independent artistic interpretation of Melbourne train culture. It belongs to Chromatica’s urban-art and transit-culture context, but that does not make it an official transport document or an operator-authorized product.
The verified information does not identify a specific:
- transport operator;
- railway line;
- route or service;
- station;
- fleet class; or
- train model.
Visual resemblance alone is not enough to assign one of those identities. Train forms, windows, doors and other details may invite comparison, especially for readers familiar with Melbourne railway culture, but a collection record should not convert resemblance into a verified attribution.
A reliable description is:
Independent Melbourne train-culture artwork from the Chromatica City Series.
Avoid descriptions such as “official Melbourne railway board,” “licensed operator artwork” or a named model attribution unless separate authoritative documentation supports them. The product is expressly presented as independent art and is not affiliated with any transport operator.
A Simple Catalogue Entry for the Melbourne Edition
The following model can be adapted to the actual number and observable condition of a board. The example edition number is illustrative; replace it with the marking on the reverse of the piece being recorded.
| Catalogue field | Example entry |
|---|---|
| Creator or brand | Chromatica |
| Series | City Series |
| Design | Design 19 Melbourne |
| Title or description | Melbourne Graffiti Train Birch Wood Art Board |
| Material | 3 mm birch wood |
| Process | Permanent laser engraving |
| Format | A4 landscape, approximately 29.7 × 21 cm |
| Edition | Worldwide edition of 25 |
| Individual number | 07/25, marked on reverse |
| Certificate | Chromatica Certificate of Authenticity supplied |
| Product reference | ET-WD-CS19 |
| Affiliation note | Independent artistic interpretation; not affiliated with a transport operator |
For a compact inventory, the same information can be reduced to one line:
Chromatica, City Series Design 19 Melbourne, permanent laser engraving on 3 mm birch wood, A4 landscape, numbered 07/25 on reverse, Certificate of Authenticity supplied.
The most important practice is simple: transcribe the reverse number exactly, keep it separate from Design 19 and avoid using either number to infer chronology, value or transport-operator identity. Read together, the identifiers establish what the artwork is, where it sits within the City Series and which numbered Melbourne board is in the collection.
