Action Comics #47 (1942)

Action Comics #47 introduces readers to Superman's infamous arch-nemesis, Lex Luthor, who devises an elaborate and dangerous plan to seek revenge against the Man of Steel after suffering a humiliating defeat from him. Luthor gains incredible super-strength and invulnerability in order to take on Superman in hand-to-hand combat. When wealthy businessman Brett Calhoun announces he will award $3 million to the wealthiest man in Metropolis, Luthor kidnaps him and takes all the millionaires hostage. He then demands that Superman retrieve the Powerstone from Skull Valley as his price for releasing them.

What happens next is a thrilling and intense story that leads up to a clever twist ending that gives Superman the last laugh. This issue is particularly significant as it features Luthor's first appearance on the cover and was published just a few weeks after the United States entered World War II. If you're a collector looking to add a classic piece of comic book history to your collection, Action Comics #47 is a must-have.
