Betty Boop is an animated cartoon character created by Max Fleischer, with help from animators including Grim Natwick. Despite having been toned down in the mid-1930s to appear more demure, she became one of the most well-known and popular cartoon characters in the world.
Her cartoons also stood out from the competition due to their upbeat jazz soundtracks. Guest bands for Betty Boop cartoons included the bands of Cab Calloway, Louis Armstrong, Rudy Vallee, and Don Redman.
