Create a vintage advertisement wall backdrop inspired by old Saigon

Create a vintage advertisement wall backdrop inspired by old Saigon, Vietnam. The backdrop should feature aged, weathered walls with faded, hand-painted advertisements in Vietnamese. Include elements like retro typography, traditional Vietnamese fonts, and illustrations from the 1950s-1970s era, such as old Grab signs, vintage motorbikes, or classic Vietnamese products like old soap brands. The colors should be muted and slightly worn, reflecting the passage of time, with a warm, nostalgic atmosphere
