Price Stern Sloan
Founded in Los Angeles in the early 1960s by Roger Price, Leonard Stern, and Larry Sloan, Price Stern Sloan began as a publisher of Mad Libs and Droodles. The company expanded into children's books, humor, and novelty formats, including titles like Mr. Men and Little Miss, Wee Sing, and various movie tie-ins. Now an imprint of the Penguin Group, the publisher continues to release Mad Libs annually, while founders Stern and Sloan later established Tallfellow Press.
