From the right foreground, a snarling stone serpent head — the feathered deity Quetzalcóatl rendered in volcanic andesite — juts into frame, its fanged jaw and spiral eye still commanding authority after fifteen centuries, while the great Pyramid of the Moon broods in soft focus across the Avenue of the Dead behind it: this is Teotihuacán at its most theatrically composed. The card was mailed during the momentous year of the 1968 Mexico City Olympic Games, as confirmed by the vivid 80-centavo purple Mexico '68 cycling stamp affixed to the reverse (Scott # likely from the Mexico 1968 Olympics set). The sender, Helen, writes with infectious enthusiasm to her friend — she has climbed both the Pyramid of the Moon and the Pyramid of the Sun, attempted to attend a bullfight only to find the matadors on strike, and is heading to the zoo before departing; she jokes she is "doing an injustice with the Spanish language." The card was published by Editorial Mexico S.A. / Fischgrund, a prominent binational publisher whose cards are eagerly collected.
