Design a mid-century travel poster for LISBON. Show its best-known landmark: a yellow tram climbing a hill of tiled houses, in simplified flat shapes with a slight screen-print texture. Palette: limited to four colours — cream, tomato red, ocean blue, mustard. Composition: landmark large in the lower two-thirds, sky with a large sun or moon disc. Text: the word "LISBON" in bold condensed sans-serif across the top, nothing else. Format: vertical 2:3. Avoid: extra text, photorealism, gradients, misspelled city name.
