Looking straight down the soaring nave of the Franciscan church of San Francisco Acatepec in Cholula, Puebla, this real photo postcard captures one of the most spiritually charged interiors in colonial Mexico — rows of plain wooden pews recede toward an explosively ornate gilded high altar, its retablo layered with polychrome saints, twisted columns, and baldachined niches beneath a ribbed Gothic vault that seems almost impossibly delicate for a structure begun in the sixteenth century. Mailed in October 1945 from Puebla to Mr. and Mrs. L.S. S. at 166 Rockingham St., Rochester, New York, the reverse carries a densely written travelogue in tiny handwriting — the anonymous sender describes visiting Taxco, a stunning 9,000-person church, Cuernavaca, a bargaining lesson at a silver shop (getting the price down from 800 to 650 to "maybe 15" pesos), Puebla's famous Talavera tiles, and a beautiful trip through the mountains, signing off warmly and promising more details back in New York.
