The game at the heart of a World War 2/Pearl Harbor conspiracy theory. Advertisements for the game that ran in the New Yorker November of 1941 referenced the possibility of hiding in air raid shelters, and featured the numbers 12 and 7 not to mention a logo that looks like the Austrian two-headed eagle! Following the attack on Pearl Harbor, the American counterintelligence community was convinced the ad had been a code to alert Japanese and German sleeper cells to the onset of war. It all turned out to be wartime hysteria. Interesting side note: following the failure of the game to sell well (it turns out that there IS such a thing as bad publicity) the man who developed it, one Roger Paul Craig, worked for the OSS, predecessor to the CIA.
