Montevideo's Palacio Salvo rises above the colorful Rambla promenade

Create a clean, modern mid-century vintage travel poster for Montevideo, Uruguay in a bold flat-vector illustration style. At the top, place the large title "MONTEVIDEO" in dark navy uppercase letters, with "URUGUAY" centered below in smaller white uppercase text.
The composition features the iconic Palacio Salvo prominently in the center, surrounded by colorful urban buildings in simplified geometric shapes. Behind it, illustrate the sweeping curve of La Rambla waterfront promenade wrapping around the calm blue waters of the Río de la Plata. Add tiny walking figures, stylized evergreen trees, and a distant skyline across the bay.
In the foreground, include a charming neighborhood of small pastel-colored houses, narrow streets, a church with a blue dome, palm trees, cypress trees, cacti, a central park with a statue, decorative coastal motifs, an anchor symbol, and ornamental border patterns inspired by South American folk art.
Use a warm retro color palette of golden yellow, burnt orange, terracotta, cream, navy blue, teal, and beige, with crisp geometric shapes, minimal shading, and strong contrast. The design should evoke a nostalgic 1930s–1960s travel advertisement, with balanced composition, clean lines, and a screen-printed poster aesthetic. Vertical 3:4 aspect ratio, ultra-high resolution, flat graphic illustration, elegant typography, and a timeless vintage travel vibe.
