A piece of news that may well have the world’s collectors on the edge of their seats: the can in question is the only remaining one of its series. The Atlantan giant, which set up its Japanese operation in 1965, says itself that it doesn’t have any stashed away in its museum. The can was probably left behind by the Japanese Antarctic expedition in the late 60s; each team member’s recreational rations included a can of Coca Cola and a few packets of the South Korean “Lotte” brand of chewing gum (number 3 in the world).
