Scarce mid-grade complete set of the 1938 R69 Gum, Inc., ‘Horrors of War’ trading cards, comprised of all 288 cards. In overall very good condition; none of the cards are creased. Card #283, depicting Adolf Hitler, is encapsulated by PSA and graded “VG-EX 4.” The ‘Horrors of War’ series is one of the most famous non-sport trading card sets ever issued, owing to its impressive and violent illustrations, which depict and describe events of the Sino-Japanese War, Ethiopian War, and Spanish Civil War. It was originally released as a 240-card set, with 48 cards later added to depict the violence in Germany and start of World War II; given their shorter print run, these last 48 cards are especially scarce.
