装饰艺术哥谭电车海报

A vintage Art Deco travel poster in a clean flat 2D 1950s-inspired illustration style, showing an elevated tram entering Gotham City at sunset. Use a tall vertical poster composition with strong geometric symmetry, sharp stepped deco framing, and no 3D relief or realistic textures. At the top, place a large angular Art Deco border in glowing peach-gold lines, with exactly 3 small circular dots centered near the top inside the frame. Inside this frame, set the headline WELCOME TO GOTHAM CITY ! in large elegant Art Deco lettering, stacked across 4 lines reading exactly: “WELCOME”, “TO”, “GOTHAM”, “CITY !”. Keep the typography crisp, centered, and integrated into the poster design. Below, create a stylized skyline of futuristic Gotham skyscrapers with tall narrow towers, stepped crowns, spires, and simplified window slits; count 12 visible building masses across the skyline. Behind the buildings, place a large glowing half-sun low on the horizon. In the foreground, show 1 long streamlined elevated tram stretching diagonally from the lower left toward the lower right, with the front car prominent on the right side. The tram should have glowing cream windows, rounded front corners, exactly 3 circular lights on the front face, and overhead electric lines with elegant sweeping cables crossing the composition. Use exactly 2 visible rail tracks curving toward the viewer at the bottom. Palette: deep indigo, violet, plum, black, peach, amber, and warm cream gradients. Mood: nostalgic, sleek, cinematic, airy, optimistic retro-futurism. Make it look like a polished mid-century flat graphic poster for urban transit tourism.
