Cuba, 1962
Rick says this map of Cuba, produced by the American-owned oil company Esso, was probably the last edition before the Cuban government nationalized Esso's oil facilities because they refused to refine state-owned oil imported from the Soviet Union. That happened in 1960. "The Cuba map is dated 1956 -- the date of revision of the map base -- but it has a printing date of 1962," Prelinger said. "It is tempting to imagine it was made for the Bay of Pigs invasion force, but I have no information this is so."
