Glittering against the Mexico City night sky, the Palacio de Bellas Artes blazes in amber and ivory light on this vivid chrome-era postcard — the great Art Nouveau/Art Deco palace looking every bit the cultural crown jewel it has been since its 1934 inauguration. Long-exposure traffic trails streak the foreground boulevards in gold, and the copper-clad dome glows as though lit from within. The sender, Barb, dashed off a breezy travelogue on November 26, 1973: she and a companion had been "royal visitors" in Mexico City, were now on their own heading to see the Mayan ruins at Tikal, reported a sunburn, and relayed that a friend named Barbara was "setting the date." The card carries a Guatemala stamp — suggesting it was actually mailed from Guatemala en route — adding a philatelic twist: the stamp depicts Fray Francisco Ximénez, the Dominican friar who discovered and translated the Popol Vuh, issued for the 1972 International Year of the Book. Addressed to Edgar and a family member in Clarkson, NY, this postcard captures the golden age of independent Latin American travel in vivid detail.
