The 1938 International Gum Don't Let It Happen Over Here set contains 24 cards depicting graphic images of events leading up to World War II, with text on the back explaining in more details the gruesome pre-war events. As these cards came on the market at the same time as the more popular Horrors of War cards, fewer of these were collected, which makes finding these cards harder today.
