复古中世纪风格旅行海报地标插画

Create a 3:4 vertical retro travel poster featuring [Country / City Name] and its representative landmark [Building / Natural Landscape Name]. The overall style adopts Mid-century Vintage Travel Poster / Vintage Lithograph / Retro Tourism Poster, referencing the visual language of classic mid-20th-century aviation, railway, and national tourism promotional posters. Main Subject: Use [Landmark Name] as the absolute visual center; the building or landscape must have real, accurate, and clearly identifiable iconic silhouettes and structural features. Naturally include auxiliary elements such as [trees / mountains / rivers / lakes / streets / city skyline / clouds / vegetation] based on the actual local environment, but do not let them overshadow the main subject. The composition is simple, stable, possessing a monumental visual sense and a collectible travel poster feel. Poster Layout: Retain a wide warm ivory / beige old paper border on all sides, with the main image placed inside a thin-line rectangular frame. At the top of the poster, use an extra-large, bold, geometric sans-serif English title: [CITY / COUNTRY] The letter spacing is slightly wide, with a deep dark green or deep blue-green ink effect. A minimalist thin horizontal line and a small geometric decorative symbol related to the local culture can be added above the title, but remain restrained and do not add redundant information. Printing Texture: Simulate real vintage Lithograph / Screen Printing / old magazine printing effects, adding fine halftone dots, paper fibers, ink particles, slight ink leakage, mild fading, faint overprint displacement, natural wear, small areas of white noise, and aged grain. Maintain a clear sense of physical printing; do not use smooth digital illustration effects or modern 3D rendering feels. Color Palette: Use a limited color palette and low-saturation retro colors, dominated by grey-cyan-blue sky, deep dark green, warm beige, ochre, terracotta orange, faded red, and warm golden sunlight. Highlights lean towards cream yellow and warm orange, while shadows lean towards deep cyan-green and blue-grey. The overall color is rich but not gaudy, possessing the synthesized tones of an old poster oxidized over time. Lighting: Soft morning or afternoon slanted sunlight, creating warm golden highlights on buildings and natural landscapes, forming a classic warm-cold contrast with the cyan-blue sky. Clouds are thick and soft, with an old printed magazine texture. Overall Temperament: nostalgic, timeless, elegant, cinematic, collectible, editorial, refined, poetic, sophisticated, archival travel poster aesthetic Image Requirements: Sophisticated composition, clear subject, natural negative space, rich details without clutter, ultra-high definition, possessing the high-end retro travel poster texture that is truly printable and collectible. Avoid: Modern commercial advertising feel, neon colors, high-saturation candy colors, smooth CG, plastic texture, AI over-sharpening, complex layout, large amounts of small text, random English, garbled characters, modern UI elements, excessive realistic photography feel, cartoonish feel, distortion of the main building.
