Istanbul Typographic Travel Poster

Create a premium editorial illustrated travel poster for ISTANBUL, built around 8 enormous tall block capital letters spelling “ISTANBUL” across a wide horizontal cream canvas. Use each letter as a vertical window filled with detailed Istanbul scenery: 1) I shows the Maiden’s Tower on the Bosphorus with a Turkish flag and ferry boats, 2) S shows hillside waterfront neighborhoods, domes, minarets, clouds, and birds, 3) T shows Galata Tower above narrow streets with a red vintage tram in the foreground, 4) A shows the Bosphorus with ferries, sailboats, bridges, and distant skyline, 5) N shows Hagia Sophia and layered mosque domes in warm peach and stone tones, 6) B shows the Bosphorus Bridge, water, a ferry, and waterfront palaces, 7) U shows steep historic streets, colorful stacked houses, greenery, and a large tree, 8) L shows Ortaköy Mosque by the waterfront with two minarets and flying seagulls. Above the title, add a thin minimalist skyline strip containing 13 small illustrated elements from left to right: trees, a small domed pavilion, a teal car, a red tram, distant city towers, a ferry, a suspension bridge, Maiden’s Tower, another teal car, a grand mosque with multiple minarets, a peach sun, a round green tree, and a final mosque minaret. Style it as a refined mid-century travel poster with clean vector-like illustration, soft muted palette of teal blue, sea green, dusty peach, terracotta, warm cream, and charcoal linework; crisp geometry, subtle paper grain, elegant negative space, tiny birds and clouds, no photorealism, no extra text besides the city name. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
