[CITY] プレミアムコレクティブル切手風ポスター

Design a '4:5' premium collectible postal-stamp poster for [CITY] blending modern philatelic design with handcrafted travel-art illustration and luxury minimalism. The poster should convey cultural pride, elegance, and destination identity through a giant postage stamp that fills the canvas edge-to-edge, framed like a national artifact. SUBJECT: A monumental vertical stamp dedicated to [CITY], illustrated in a refined handcrafted style - hybrid of gouache, silkscreen poster art, and premium editorial illustration. Capture the city's defining atmosphere: architecture, skyline, nature, iconic transport, cultural motifs, or urban density. Avoid literal tourist clichés; simplify landmarks into elegant graphic forms. Perforation edges are large, tactile, and part of the visual identity. Surface should feel physically printed and collectible. COMPOSITION: The stamp itself is the full composition. Viewers enter via the oversized city name, then move through layered depth. Use asymmetric scenic flow with dominant elements rising diagonally and secondary forms wrapping around. Include intentional negative space for premium restraint. Thin elegant borders with subtle engraved linework and tiny postal marks. Perforation edges touch all sides for immersive, object-focused design. TYPOGRAPHY: Main text: [CITY] massive, integrated into the stamp, using high-contrast serif or geometric sans-serif depending on city character. Minimal additional text: tiny denomination, subtle 'AIR MAIL' or 'POST', micro issue year, optional country line. Typography should feel printed, not digital. LIGHTING / PRINT: Luxury print-style lighting with soft highlights, tactile paper grain, embossed ink, subtle shadow around perforations. Focus on collectible realism. COLORS: Palette reflects [CITY] while remaining vibrant yet restrained. Balance one dominant color, one accent, and a neutral paper tone. Avoid random rainbow palettes. STYLE & FINISH: Handcrafted luxury illustration blended with modern editorial travel branding. Ultra-clean premium print finish: tactile texture, subtle embossing, refined ink, delicate edges. Feels collectible, museum-quality. FOOTER: Integrate a tiny engraved postal info strip into the bottom border with micro typography, serial numbers, and cancellation marks. NEGATIVE: Avoid generic travel posters, postcard clichés, floating landmarks, cluttered collages, excessive text, fake vintage distress, noisy textures, over-detailed realism, stock icons, random gradients, cheap souvenir aesthetics, basic centered layouts, or low-detail illustrations.
