Retro American Pop / 1950s Poster

Full style prompt

For beginner-friendly talks that should feel like mid-century ads + comics. Look: Heavy black outlines, big flat color fields, halftone print texture, aged cream paper; palette red, green, yellow, beige, loud contrast; multi-panel or column infographic — top hero headline + icons (megaphone, gift, button, arrows), bottom short copy; reads as retro marketing poster / Pop Art infographic, not vanilla corporate.
