Margaret Brundage (b. 1900 - d. 1972) was an American illustrator and painter who is best remembered for her artistic contributions to pulp magazines, most notably the pulp covers for Weird Tales from 1933 to 1938. The majority of the magazine's readers had no idea she was female, as she signed her pieces "M. Brundage," and complaints about the erotic nature of work increased only after it was revealed that "M" stood for "Margaret."
