A dusty frontier Main Street frozen in early-1920s amber — unpaved roads, early-model Ford-era automobiles, a zebra-striped burro posing for tourists near a sporty open-air touring car, and wooden storefronts hawking curios to Americans eager for a taste of Mexico just across the San Diego border. The colorized view looks north along Tijuana's main commercial strip, where "Mitchel & Mouren Curios" and the "Hotel de Paris" anchor the left side, while "The Big Curio Store" (proprietor Jorge Ias.) dominates the center — its open porch draped with Saltillo blankets and serapes. A Mexican tricolor flag snaps in the breeze over the right-side arcade. This was Tijuana during Prohibition's golden tourist boom, when thousands of Americans streamed south for gambling, drinking, and souvenir shopping. On the back, a terse note from an unnamed sender was mailed to E.H. (first name initial only) Westbrook of Hemlock, New York: "I am here today at 11am June 17 — Some town." Published by I.L. Eno of 959 5th St., San Diego — a key regional postcard house of the era.
