Three-Color Mid-Century City Travel Poster

Create a vertical mid-century travel poster for [CITY NAME] featuring [LANDMARK OR DISTRICT]. Use a strict three-color palette only: cream paper, black technical linework, and [ACCENT COLOR]. The style should be a minimalist isometric bird's-eye city illustration with ultra-fine hatching and a screen-print texture, with no gradients. Fill the sky with a solid [ACCENT COLOR] and reuse it sparingly on roofs, streets, or small details. Place a bold sans-serif [CITY NAME] at the top, followed by a smaller local-language subtitle. The final image should feel print-ready: restrained layout, readable text, crisp edges, no gibberish, and no watermark.
