پوستر هشدار شست وشوی دست با پزشک طاعون

Create a vintage public health warning poster in a distressed black-and-white engraved print style. Centered portrait of a plague doctor wearing a wide-brimmed hat, long beaked mask, high layered collar, and formal dark coat. Use detailed cross-hatching, etched linework, halftone texture, worn paper grain, faded ink, scratches, distressed borders, and an antique historical print aesthetic. Add a strong horizontal divider near the bottom and large bold uppercase block lettering that reads exactly: "WASH YOUR HANDS". High contrast, symmetrical composition, dramatic frontal pose, minimalist dark background, authentic retro warning poster design, readable typography, no other text, no logos, no watermark. Vertical poster layout, aspect ratio 3:4.
