Flat Geometric Minimalist Destination Poster

Create a premium minimalist illustrated travel poster of [Lisbon] in a strict [4:5 vertical] aspect ratio. Build a centered, balanced composition around the destination's most iconic landmark, landscape, or cultural feature, adapting naturally to the location. Use strong black hand-drawn outlines, simplified geometric shapes, a refined limited palette of [terracotta, cream, ocean blue and soft yellow], subtle paper grain, and clean flat colors. Include a clear horizon line, atmospheric depth, and a few tiny human figures or local details for scale and character. Combine a vintage travel-poster aesthetic with modern editorial illustration: elegant, playful, sophisticated, and highly recognizable. Maintain generous negative space, clean visual hierarchy, crisp edges, restrained detail, and a handcrafted printed-poster feel. Avoid clutter, photorealism, excessive gradients, and unnecessary elements. Add "[Lisbon]" in uppercase using simple [typewriter-style] lettering, positioned subtly within the composition without overpowering the artwork. Strict vertical composition - no other aspect ratio.
