The phenomenon of "trophy-taking" was widespread enough that discussion of it featured prominently in magazines and newspapers, and Franklin Roosevelt himself was reportedly given, by a US Congressman, a gift of a letter-opener made of a man's arm (Roosevelt later ordered that the gift be returned and called for its proper burial). The behavior was officially prohibited by the U.S. military, which issued additional guidance as early as 1942 condemning it specifically. Nonetheless, the behavior continued throughout the war in the Pacific Theater, and has resulted in continued discoveries of "trophy skulls" of Japanese combatants in American possession, as well as American and Japanese efforts to repatriate the remains of the Japanese dead.
