Composition order: sky fill at top, landmark as the central focal point, city typography anchored at the top edge. </format> <tone> Clean, confident, and design-forward, with the nostalgic warmth of 1950s–1960s European and American tourism advertising. </tone> Generate the poster image now using [CITY NAME] and [LANDMARK] with accent color [COLOR].
