In November 22, 1941, The New Yorker published an advertisement titled "Attention, War, Alarm," featuring a game called "Double Death" dice. After Japan's attack on Pearl Harbor, some speculated that this ad was related to the date of December 7, even suggesting it was a conspiracy by the Axis powers. However, Roger Craig's widow denied this claim, asserting it was merely a coincidence.
In 1944, the Allies planned to invade Europe under the codename "Overlord." Surprisingly, these codenames appeared in a crossword puzzle in the London Daily Telegraph just before the operation began. British security personnel initially suspected that a Nazi spy had leaked the information, but it was ultimately determined that the puzzle's creator, Leonard Dole, had come across the names purely by chance.
