# Style descriptors only. This prompt names no artist, studio, brand or work.

Produce four original images in the visual language of Onchi Kōshirō Book Design, a style from Publishing and Editing, 1910s–1950s.

## What to make

Make the kind of thing this style exists for: covers for poetry and collected works made as a print rather than as a holder for a picture, or few color printing where even the title lettering belongs to the image surface. Choose one subject and hold it across all four images.

## What has to be visible

- Covers built only from abstract shapes and flat colour, with no representational illustration
- Title lettering drawn by hand rather than set in type, sitting on the same surface as the image
- Few colours, with form made by overlapping planes instead of outlines
- The bare colour of the paper left showing, with the image laid straight onto it

Someone who knows this style should be able to point at each of these in the finished image.

## How to build it

- Layout and structure: The cover composed as one surface rather than as a picture with lettering added to it
- Type and lettering: Title lettering drawn by hand instead of set in type, on the same surface and at the same weight as the image
- Material and surface: Few colors and no outlines, form made by overlapping planes, the bare paper left showing and counted as one of the colors
- Colour: #f4e2cc carries the ground, #cc7c26 is the colour the style is remembered by, #0e0e0c holds text and outlines. Read off real works, so treat them as a direction rather than a fixed palette.
- What it should feel like: luxury, intimacy, calm

## What goes wrong

Setting a representational picture into a frame turns the cover back into a place to put a picture, and the surface stops being a print.

## Across the four

Keep every cue above present in all four. Vary the framing, the scale and the arrangement so the set shows the range this style covers rather than four versions of one picture.

## Constraints

- Do not imitate, reference or name any specific artist, studio, brand, character or copyrighted work.
- Do not reproduce the composition of an existing work.
- Produce original compositions in the general period language described above.
