A shaded lane of orange trees leads past a row of gleaming white stucco bungalows at the Colonial Courts tourist camp — Kilómetro 477 on the Pan-American Highway north of Ciudad Valles, San Luis Potosí — in this warm linen-era advertising card that captures the optimism of mid-century automotive tourism in Mexico at its most inviting. The back copy reads like a roadside dream: "Hotel, Restaurant, Bar, Tobacco Shop, Mexican Curios, Tennis Courts, Gasoline Filling Station, Children's Playground… pure, invigorating air, perfect quiet, comfortable Simmons beds and excellent meals… over a height dominating a splendid panoram." Colonial Courts was one of the key stopping points for American motorists making the long drive down to Mexico City on the newly completed Pan-American Highway in the 1940s and 1950s, and this unused card with its lush hand-colored imagery documents that vanished travel infrastructure beautifully.
