Mopsy was a comic strip created in 1939 by Gladys Parker, who was one of the few female cartoonists of the era. The strip had a long run over three decades. Parker modeled the character of Mopsy after herself. In 1946, she recalled, "I got the idea for Mopsy when the cartoonist Rube Goldberg said my hair looked like a mop. That was several years ago, and she has been my main interest ever since."
