Robert Riggs (1896-1970) was born in Decatur, Illinois, and studied at Milliken University, the Art Students League in New York, and the Académie Julian in Paris. After serving in World War I, he worked as a commercial illustrator and artist in Philadelphia. He was a member of the National Academy of Design and taught at the Philadelphia College of Art.
All three of his Post covers feature factory scenes during World War II, but Riggs was known primarily for his works depicting boxers, circus life, and domestic violence.
