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. Birth and early career George Petty was born in Abbeville, the seat of Vermilion Parish in south Louisiana to George Brown Petty III and his wife, Sarah. George, IV, was the couple's second child; his sister Elizabeth had been born in 1891. The Petty family moved to Chicago, Illinois, just before the turn of the century, where George, III, a photographer of some note, enjoyed considerable success with images of young women, madonnas, and nudes. Petty was not a particularly good student in high school, spending a great deal of time on extracurricular activities instead of schoolwork. His artistic bent first became obvious in high school, where he was the staff artist for the school newspaper. During his high school years, he enrolled in evening classes at Chicago Academy of Fine Arts under the tutoring of Ruth VanSickle Ford, where he taught his own art course, charging classmates $5.00 per session. He also worked in his father's photo shop where he learned how to use an airbrush. In Paris, Petty studied art at the Académie Julian with Jean-Paul Laurens and others until 1916, when World War I caused Myron T. Herrick, ambassador at that time, to order all Americans to return home. Petty returned to Chicago, and worked as an airbrush retoucher for a local printing company. He was able to establish himself as a freelance artist, painting calendar girls and magazine covers for The Household. By 1926, he was able to open his own studio. Artistic influences George Petty never discussed in detail those artists who influenced him, other than J. C. Leyendecker (an artist for The Saturday Evening Post during George's high school days) for his interpretation of men, Coles Phillips for his technique, and Maxfield Parrish for his use of light. However, it can be inferred from his later work that other influences included artists who were extremely popular in Paris at the time, such as Alfons
