Action Comics #29

In "The Life Insurance Con," Superman faces a cunning scam that plays on people's trust—just as the radio waves carry his adventures to listeners across the Northeast, with a special broadcast in Arizona sponsored by Martin Oil and Gas Co. This early story, drawn by Joe Shuster, captures the character's growing cultural presence, while the cover by Wayne Boring showcases the Man of Steel in a moment of quiet determination, a 10-cent comic in 1940 that helped bring Superman into American homes.
