Palm trees arch over an ornate stone fountain in the foreground as the grand Beaux-Arts façade of the Hotel Ancora rises behind them — vintage automobiles from what appears to be the late 1930s or early 1940s parked along the curb confirming the era — in this rare hand-colored real-photo postcard from Monterrey, Mexico, one of the city's most celebrated lodgings of the mid-twentieth century. Margaret sent this to "Sil, Doc, and Family" at 532 Hudson Ave., Rochester, N.Y., urging them to make "romantic and picturesque Mexico your next trip" and noting that once you get into the heart of Old Mexico, "it is vastly different than the border towns" — a sophisticated traveler's observation that still rings true. The partially legible ambulante (traveling mail) postmark is an unusual philatelic feature, indicating the card was posted on a railway mail car rather than a fixed post office, a detail that adds collector interest beyond the image itself.
