Vintage mascot poster in a vertical 4:5 layout on a cream paper background using only [COLOR1], [COLOR2], [COLOR3], and [COLOR4]. At the top, place the bold rounded headline “[TITLE]”. In the center, show a rubber hose style [HUMAN] wearing [CLOTHES] walking beside [ANIMAL] through [BACKGROUND], both with pie-cut eyes, simple smiling faces, thick clean outlines, rounded limbs, oversized shoes, and a playful mid-step pose. Add subtle register misalignment in the outlines and fills, light distressed screen-print grain, a simple circular stamp graphic, and a horizontal checker stripe near the lower section. At the bottom, place the bold rounded tagline “[TAGLINE]”. Clean retro t-shirt graphic, flat colors, no gradients, crisp simple composition.
