Diners linger over white-linen tables on a sun-dappled terrace while the twin Churrigueresque towers of Santa Prisca cathedral preside over the silver-mining town of Taxco, Guerrero — one of Mexico's most photogenic colonial hill towns. The chrome-era color saturates every terra-cotta pot and cobalt-blue chair, conjuring the relaxed glamour of mid-century Mexican travel. On the back, a traveler named Bonnie dashes off an enthusiastic note to a Milwaukee friend: "This is where we stayed Monday nite. Beautiful country & a delightful place. Drove to Acapulco Tues. Arrived 1:30. The hotel is lovely. Going shopping this afternoon. The sun is so hot — cold better. All my love, Bonnie."
