Use the image I've attached. Turn it into a 1960s pop-art silkscreen print, repeated four times in a 2 by 2 grid, with the same subject, pose and crop in every panel. If there are people in it, keep their faces, features, hairstyles and expressions recognizably theirs. Style: the photo reduced to a high-contrast black screen layer of shadows and key lines, printed over flat, bold blocks of color; each panel in its own color scheme, such as hot pink with lime, turquoise with orange, yellow with violet, and red with sky blue; the black layer printed slightly off-register, so color peeks out past the edges; flat, unshaded ink with the faint mesh texture of the screen and a few small ink skips; thin white gutters between the panels. Keep each face in a flat tone close to that person's real skin tone, and put the bold color swaps in the background, hair and clothing. Avoid gradients, 3D shading, comic dots and speech bubbles. No text, logos or watermarks. Format: {{aspect_ratio}}.
