Puck was a pioneering American humor magazine that ran from 1871 to 1918. Founded by cartoonist Joseph Keppler in St. Louis, it later moved to New York City where it gained national prominence. Known for its witty political satire and colorful cartoons, Puck was the first successful humor magazine in the United States to feature chromolithography. The magazine's mascot was Puck, the mischievous character from Shakespeare's "A Midsummer Night's Dream," and its motto was "What fools these mortals be!" Puck's sharp commentary on social issues, politics, and current events made it a significant influence on American popular culture during the Gilded Age and Progressive Era.
