Moon Mullins Moon Mullins, created by cartoonist Frank Willard, was a popular American comic strip which had a long run as both a daily and Sunday feature from June 19, 1923 to June 2, 1991. Syndicated by the Chicago Tribune/New York News Syndicate, the strip depicts the lives of diverse lowbrow characters who reside at the Schmaltz (later Plushbottom) boarding house. The central character, Moon (short for Moonshine), is a would-be prizefighter—perpetually strapped for cash but with a roguish appetite for vice and high living. Moon took a room in the boarding house at 1323 Wump Street in 1924 and never left, staying on for 67 years.
