Jungle-framed and sun-drenched, the Temple of the Inscriptions at Palenque rises nine terraced tiers above a stone plaza, its steep central staircase climbing to a roofcomb-crowned sanctuary that sheltered the tomb of the great Mayan ruler Pakal—a discovery made just two decades before Charlotte and Bob passed through on a February 1973 road trip through southern Mexico. Their postcard, mailed Monday the 19th, fizzes with tourist energy: they'd spent a day among the ruins "a couple of days ago," climbed those very steps, then explored interiors "an equal number inside to a tomb," before heading to Uxmal the next day, marveling that the Maya had "quite a sophisticated culture." Now in Mérida and planning a lazy afternoon poolside, they close with a breezy note—"It is Hot — but beautiful"—to a Mrs. Edgar Bockes in Fairport, New York. The vivid Vistacolor chrome print, photographed by Vicente Kramsky and published in San Cristóbal de las Casas, captures the monument in the warm golden light that still greets visitors today.
