复古低多边形旅行海报

Create a refined vintage tourism poster for [LOCATION], combining the visual language of a premium mid-century travel brochure with sophisticated low-poly 3D illustration.

FORMAT & COMPOSITION: Vertical 4:5 Instagram poster. Cream/off-white aged-paper background with subtle grain. Strong, balanced editorial composition. Large destination name at the top in bold distressed navy uppercase. Smaller country/region name beneath. Elegant tagline: "THE GATEWAY TO [REGION / LANDMARK]". Small "EST. [YEAR]" detail where appropriate.

MAIN ILLUSTRATION: Create a large central scenic panel featuring the most iconic and instantly recognizable view of [LOCATION]. Use low-poly 3D geometry with clean triangulated surfaces. The landscape should feel like a premium miniature diorama — mountains, buildings, water, trees all rendered in faceted geometric forms. Maintain a cohesive color story drawn from the location's natural palette.

STYLE: Mid-century screen-print aesthetic with modern low-poly rendering. Muted vintage tones with one strong accent color. Subtle paper grain overlay. No photorealism — this should feel like a collectible printed poster.
