Seoul's ancient palaces and modern towers blend in vintage poster

Create a vintage editorial-style travel poster of South Korea on an aged cream parchment background. Place the gold serif title "SOUTH KOREA" at the top with a Taegeuk emblem beneath and the tagline "CRAFTED THROUGH DYNASTIES", framed by golden ginkgo leaves and pink-white Mugunghwa flowers. In the center, feature large gold-trimmed serif letters spelling SEOUL, with each letter revealing a scene: Gyeongbokgung Palace with women in hanbok, Dongdaemun Design Plaza, Namdaemun Market, an Insa-dong hanji paper artisan, and N Seoul Tower. At the bottom, blend traditional palace gates, hanok shops, a vintage kiosk, modern skyscrapers, N Seoul Tower, and a white-gray light rail tram. Include a stylish retro-dressed couple walking arm-in-arm alongside people in hanbok on a stone-paved street. Add the Hangul sign "서촌 공방" on a hanok storefront and place the coordinates 37.5665° N, 126.9780° E centered at the bottom. Use a warm muted color palette, elegant vintage typography, detailed travel-poster illustration, soft textures, and a timeless 1950s retro aesthetic.
