A fleet of rounded-fender late-1930s American automobiles crowds the forecourt of the Tijuana Custom House — its white Art Deco facade, red-trimmed arcade, and Mexican tricolor snapping overhead — in a linen postcard that crystallizes the border-crossing experience of the pre-war tourist era. Produced by the Japanese-printed Exportadora e Importadora S.A. and photographed by "Photo Mantel," this card captures a moment when Tijuana was booming as a playground for American visitors, the cars a perfect automotive time capsule of 1938–1940 models. "Joe" mailed this to his friend "Dick" at a North Winchester Street address in Chicago on May 24, 1941 — seven months before Pearl Harbor would change everything — writing simply that he was enjoying Mexico very much and wished Dick could be there. The Mexican Revolution Anniversary 4c stamp is cleanly cancelled with a Baja California postmark.
