 Jack Frost's four stories were originally untitled, but comics historians refer to them as "The Origin of Jack Frost", "The Mechanical Octopus Pirates", "The Ambulance Racketeers" and "The Adventure of the Frozen Corpses".In addition to the four comics stories in "U.S.A. Comics", Jack also appeared in a two-page text feature written by Lee in issue #2, "When U.S.A.Heroes Meet!"
