George Brown Petty IV (April 27, 1894 – July 21, 1975) was an American pin-up artist. His pin-up art appeared primarily in Esquire and Fawcett Publications's True but was also in calendars marketed by Esquire, True and Ridgid Tool Company. Petty's Esquire gatefolds originated and popularized the magazine device of centerfold spreads. Reproductions of his work, known as "Petty Girls," were widely rendered by military artists as nose art decorating warplanes during the Second World War, including the Memphis Belle.
