Swiss Minimalist Playground Poster

Full prompt

A vertical Swiss-style minimalist graphic poster on a pristine pure white ground, combining bold black single-line contour drawings with flat, high-saturation color blocks in primary red, sunny yellow, lake blue, and grass green in a playful Memphis design language. Prominent bold sans-serif header reading "Design YIBIHUI" anchors the top, accompanied by refined graphic design editorial subtitle marks. Scattered across the center are geometric asymmetrical color patches layered with clean black outline illustrations of playground rides: a slide, seesaw, merry-go-round, playhouse, and rocking pony. Minimalist directional arrow symbols point from the four corners, while side margins display vertical typographic tags: "Branding Poster Editorial" and "Package Character Logo". Bottom footer features structured editorial typography stating "since 2026.08.03" alongside minimalist contact information placeholders. Crisp flat 2D vector execution without gradients or drop shadows, high-definition art paper print texture, aspect ratio 9:16, no author signatures, no watermarks, no brand logos.
