It's interesting to notice that in 1959, the taco was not sufficiently well known in the U.S. for Life to refer to one without both italicizing the word as a foreign borrowing, and providing a brief definition.
Lest you be left only with the strange mental image of a "somewhat dazed" Soviet emmisary eating a taco, behold a full-page photograph of Miyokan, looking rather out of sorts, eating a taco:
Even for the ruling elite of the USSR, the taco is approached in a brief encounter, surfacing as trauma.
