The Playboy magazines scattered throughout the game are all anachronistic; the game takes place between 1945 and 1951, but Playboy Magazine was not founded until 1953, and the images placed in the game were published between 1958, seven years after the end of the game, to 1968, seventeen years after the end of the game. The 19 Playboys added in the DLC "Joe's Adventures" range from 1960 to 1969, with a single image added from 2007, fifty-six years after the setting's era.
