Create a finished graphic design: a poster in A3 portrait (1:1.41) format. It is for: Burger truck weekly pitch at a brewery car park.

STYLE: Sticker Cartoon Pop
A cartoonist's brush ink poster: thick, uneven black brush outlines with flat spot colour fills printed slightly off the lines, on cheap newsprint.
Signature moves to keep:
- thick black outline on every item
- hard offset shadows
- grid backdrop
- hand pointing at the hero
- sticker tags like SOLD OUT

SUBJECT
Show Burger truck weekly pitch at a brewery car park in this style. Make the subject the hero and fit everything to it: props, setting and details should belong to this subject, not to the example the style came from.

COMPOSITION
One hero prop in the middle, held or pointed at by a cartoon hand, surrounded by three or four smaller labelled objects tilting around it like stickers. Title at the top in outlined chunky letters, a strip of small info at the bottom on white.

TYPOGRAPHY
Chunky outlined lettering in yellow or pink with a black outline and a hard offset shadow, small rounded caps labels on sticker tags.
Render exactly these words, spelled exactly as written, and no other text anywhere:
- headline: "Smash Friday"
- second line: "Double smash burgers, truck number 7"
- small details: "Every Fri 16 to 22, Brewhouse Yard"
Give them a clear hierarchy: the headline large and dominant, the rest much smaller.

COLOUR
Palette: #2F6BE3, #F6C61A, #E23B3B, #F58FB8, #2E9B4A, #111111. Cobalt blue grid ground with yellow, red, pink and green props, all outlined black. For a brand, put the brand main colour in the grid ground and recolour the hero prop to match the brand accent.

TEXTURE AND FINISH
Flat vector with a fine speckled print grain over everything, tiny misregistration of the black line.

AVOID
- sticker sheet look with white outlines
- faces on food
- glossy vector clip art
- gradients
- soft realistic shadows
- plastic 3D sheen
- thin outlines
- lens flare
- anything that looks AI generated: plastic sheen, airbrushed skin, overly smooth gradients, glow and lens flare, HDR, stock photo smiles
- gibberish letters, made up words or any text other than the exact words given
- watermarks, signatures, UI elements, borders or frames around the design
- filler decoration: sparkles, floating dots and stars, confetti, random geometric shapes, gradient orbs, ornamental dividers
- uniform line weight, plastic or airbrushed shading, soft storybook gloss, perfect symmetry, melted or merging details, impossible objects
- showing the design as a mockup (a poster on a wall, a phone, a hand holding it): the artwork itself must fill the whole canvas edge to edge, flat and straight on

Do not search the web or look anything up: work only from this brief, so nothing from elsewhere leaks into the design.
Make the image now, in A3 portrait (1:1.41) format, without asking questions first.

Questions

Can ChatGPT make a real a brush ink cartoon print?

It makes an image that imitates the look. For a physical version, use the image as artwork and take a print file to a printer that can reproduce the medium: a cartoonist's brush ink poster: thick, uneven black brush outlines with flat spot colour fills printed slightly off the lines, on cheap newsprint..

What size should I ask for?

This style is set up for poster (A3 portrait), Instagram post (4:5), square post, story (9:16), flyer (A5). Name the format in the prompt, as the examples do, and the layout follows it.

Why do the words come out wrong?

Image models draw letters as pictures, and they sometimes get them wrong. Keep the words short, put them in quotes, and check every letter. In OpenTempl you can leave room for the words and add them as live text.
