One City, One Number

A modernist travel poster built to be the second of forty — a cut-out landmark, the city set enormous behind it, and a numbered index line that only makes sense as part of a run. Six fields.

Two runs of the same template. Number 02 beside number 07, built to the same fixed list — one bone ground, one grotesque, the index at the upper right, the caption at a third width. Only the subject, the photograph, the caption and the accent change, which is what makes two posters a run rather than a resemblance.

Generated from this template with the fields shown above — hard-cut window against flat bone, the name set enormous with the photograph passing through the gap between B and A so every letterform survives whole, one blue arc, the index at the upper right. It took three runs and both failures were instructive. The first printed the fixed and free lists onto the poster itself, because a specification field sitting among content fields reads as content; the template now says plainly that neither list is printed. The first two both misspelt the subject — VIDARY, then VIBRY — and both times the error fell exactly where the window crossed a letter's stroke, so the fix was a composition rule rather than a plea: the overlap falls between letters, never across one.

One City, One Number

Produce ONE image: a modernist poster designed as one of a numbered run. Follow every line below. Replace only the FIELDS block; everything after it is fixed.

First — do you have the fields?

If any field below still has braces around it, stop and ask. Put all the questions in one short message, and show the example under each one so they can see the shape of a useful answer. Wait for the replies, then draw. Never fill a brace yourself: a value you invented is a value nobody asked for, and it will look exactly as considered as the ones they did give you.

Ask in whatever language they are writing to you in. Translate the questions and the examples; do not make someone read English to tell you what they want.

The examples are only examples. If someone answers a question, use their answer; never fall back to the example because you prefer it.

If the fields are already filled in, ignore this and carry on.

Fields — replace these six lines only

  • The subject, set large: {the name, in capitals} e.g. VIBARY
  • The local name and the region: {a second name, and a place} e.g. the library district · built on the open web
  • The number in the run: {nn of nn} e.g. 02 of 40
  • The photograph, hard-cut: {what it shows, cut from its ground} e.g. a tall studio window at dusk with one lit desk behind it, cut out cleanly along the frame's edges, no background left attached
  • The caption: {one or two sentences} e.g. A place assembled out of descriptions, where the plans stay visible after the thing is built.
  • What holds still, and what may change: {the fixed list, and the free list} e.g. fixed: a warm bone ground, one grotesque family, the number at the upper right, the caption at a third of the width · free: the accent colour, the geometry, the crop

The series law

Templates in this style describe one beautiful sheet. That is why the second poster never matches the first: nothing was declared constant, so every choice gets remade.

The last field is the design. It names two lists, and the poster must honour both:

  • Fixed — the ground colour, the type family, the corner the number sits in, and the width the caption sets to. These are identical on every poster in the run, whatever the subject.
  • Free — the accent colour, the geometry, the crop, the photograph's placement. These change every time, and they are what stop forty posters looking like one poster reprinted.

A series is defined by what does not change. Decide it before the first poster and the next one is easy; leave it implied and there is no run, only a resemblance.

Neither list is printed. They are the specification the poster is built to, not content — a poster carrying its own build notes is a spec sheet. The only texts on the page are the four named under The type.

The photograph

  • Hard-cut, never faded. The subject is silhouetted crisply against the ground with no vignette, no feathered edge, no gradient fading it out. Its own light and colour stay intact.
  • One photograph only. It sits off-centre and overlaps the type, passing in front of some letters and behind others, which is what builds depth without any effect being applied.
  • Nothing of its original background survives the cut.

The type

  • The subject in a heavy grotesque, set enormous — wide enough that the photograph interrupts it. Letters may be partly hidden; the word must still read.
  • The overlap falls between letters, never across one. The photograph's edge passes through a gap in the word, so every letterform survives whole even where the picture sits in front of it. An image cutting through the middle of a letter is how a name loses one: two runs of this template returned VIDARY and VIBRY, both times at the exact point the window crossed a stroke. Place the cut in a space, and count the letters in the result before shipping.
  • The local line small beneath the cut, in the same family, tracked wide.
  • The number in the corner the fields name, the smallest type on the page, set as an index — "02 / 40" — hard against the margin.
  • The caption in three or four lines at the stated width, low and to one side, ragged right, set at reading size rather than captions size.

The ground

  • A pale, low-saturation colour: bone, cool white, fog blue, sand, pale grey-green. Flat, or with the faintest smooth tonal shift.
  • Nothing aged. No paper texture, no speckle, no grain, no film noise, no print distress. This style is clean by definition, and every one of those effects is the failure mode it is defined against.
  • One flat geometric block or arc in the accent colour, placed to anchor the photograph — behind its lower edge, or aligned to one side. One only.

Never

  • ✕ vintage texture, distress, grain, torn edges, aged paper
  • ✕ a soft-edged or faded photograph
  • ✕ a second accent colour, or a gradient
  • ✕ the number set as decoration rather than as an index
  • ✕ extra text — no strapline, no logo row, no date block, and never the fixed or free lists themselves
  • ✕ a misspelt subject: the name is the poster, so check it letter by letter before shipping the run
  • ✕ changing anything on the fixed list between posters in a run

The result

A poster that is legible alone and unmistakable in a row: a hard cut, a name set large enough to be interrupted, a caption that reads like a paragraph, and a number small enough to trust — with the parts that must not move written down where the next designer can see them.

The whole template, in one piece. The steps below are the entire workflow.

How to use it

  1. Copy the whole template with the button above.
  2. Replace the six FIELDS lines. Write the last one first — deciding what holds still is the design, and everything after it is decoration.
  3. Paste it into any image-capable agent or model, in one message. One run returns the poster.
  4. For the next in the run, change only the subject, the photograph, the caption and the number, and leave the fixed list untouched. Two posters that share it will hang together; two that do not are a coincidence.

Before it runs

  • A subject that photographs as a silhouette. A hard cut needs an edge; haze and sky do not survive it.
  • A run in mind. The number is a promise, and '01 of 1' is a poster pretending to be a series.
  • The discipline to leave the fixed parts alone on the second one. A series is defined by what does not change, and that is the rule everyone breaks by poster three.

When to reach for it

When one poster is really a series: cities, seasons, releases, chapters. The genre's templates describe a single beautiful sheet and leave out the thing that makes a set — which parts hold still while the subject changes.

What changes

  • One clean modern poster: a hard-cut photograph of the subject, its name set enormous behind or through it, on a pale ground with no vintage texture anywhere.
  • Four elements are declared fixed across the whole series — the ground, the type family, the number's corner, the caption's width — so a second poster sits beside the first without adjustment.
  • The photograph is cut, never faded: a crisp silhouette against flat colour, which is what stops the style sliding into stock-photo softness.
  • The number is set as an index, small and unmissable, because a series without visible counting is just a folder.
  • Everything else — the accent colour, the geometry, the crop — is declared free to change, so twenty posters share a system without repeating a picture.
