Americas first cartoon flapper icon.
The first appearance of Betty Boop was in the 6th Talkartoon starring Bimbo, entitled "Dizzy Dishes" (1930.) Grim Natwick was the first animator to draw Betty, who had not yet been officially named. He took inspiration for Betty's spit curls from a song sheet of Helen Kane, commonly called the "Boop Oop a Doop Girl".
Betty started out being designed as a human-like dog, only her black button nose and floppy ears hinting at her canine nature. These ears later became her round earrings, in part due to the fact that the Fleischer animators had a tendency to change animating styles and features of characters from cartoon to cartoon, and sometimes within the same cartoon. In "Bum Bandit"-1931- Betty's nose changes from black to white and then back again in the same cartoon.
Her high baby voice, like her spit curls, were in imitation of singer Helen Kane. Her first starring role was in "Betty Coed" (1931), which also marked the first time the name Betty was connected with the character. In "Any Rags" (1932), Betty became completely human, and her ears permanently became earrings. As for her famous garter, Betty started out with two, then early drawings showing her still with ears show the garter on her right leg. When she became a regular, however, and her features were officially set, the garter moved to her left leg, and stayed there.
