Create a vintage mid-century travel poster illustration of San Francisco, California, in a refined 1950s–1960s screen-printed style. Use a tall vertical composition with a warm cream paper background and elegant dark navy typography at the top reading “SAN FRANCISCO”, with widely spaced letters, and smaller “CALIFORNIA” underneath.

Feature iconic San Francisco landmarks arranged as a stylized scenic collage: the Golden Gate Bridge in International Orange on the left, the Transamerica Pyramid prominently centered, Coit Tower on the right, and the Palace of Fine Arts rotunda in the lower-right foreground. Include Alcatraz Island in the distant lower-left bay.

Add rolling blue-gray hills, dense layered green foliage, sculpted trees, and a winding cream-colored pathway leading through the foreground toward the landmarks. Include a calm blue sky with a few simple cream-colored clouds. Use flat geometric shapes, subtle paper grain, slightly muted vintage colors, clean edges, minimal shading, elegant proportions, and a nostalgic screen-print texture.

Overall aesthetic: sophisticated retro tourism poster, minimalist mid-century graphic design, hand-illustrated appearance, balanced composition, soft desaturated palette, archival print texture, charming and timeless, high detail, no photorealism.

Aspect ratio: 2:3 vertical.
