The crypt contains voice recordings of leaders from the 1930s, including Adolf Hitler, Joseph Stalin, Franklin D. Roosevelt, and Mussolini. The sounds of Popeye the Sailor Man and a professional pig caller were stored inside the crypt. Peters, the archivist, placed electric microfilm readers and picture projectors in the chamber to allow future generations to view and listen to the recordings. He also provided a windmill to generate electricity to run the devices, as well as a magnifier for the microfilm records, should electricity not be in general use by the 82nd century. Engraved steel panels of the "Atlanta Journal" newspaper showing reports from the first year of World War II, were also placed in the crypt.
