Art Deco Retro Gentleman Poster

Design a production-ready image prompt centered on an Art Deco retro gentleman poster portrait. Define the editable hero subject, setting, supporting props, composition, camera angle, lighting direction, color palette, material textures, aspect ratio, and intended delivery use. Keep identity, anatomy, expression, pose, wardrobe, and style consistent, with editable details that can become a character sheet, portrait asset, or social creative. Keep the reference direction while turning it into a reusable creative brief: make the subject clear, keep all copy and marks editable, and leave room for brand adaptation. Avoid distorted typography, fixed logos, real brand names, celebrity likenesses, protected characters, unsupported claims, cluttered backgrounds, mismatched props, and elements unrelated to the Art Deco gentleman poster concept.
