Retro Pop-Art Poster Comic Book Style

Create a bold pop-art poster illustration in a vintage comic-book style with strong graphic contrast, halftone dot textures, and rough ink outlines. Use a limited but striking color palette dominated by red, yellow, black, and beige tones. The subject is centered, wearing oversized round sunglasses with tinted lenses. Add a gritty, textured background with splatter effects and halftone patterns, giving a retro propaganda poster vibe. High-detail illustration, screen-print texture, dramatic lighting, graphic poster composition.
