Winchell's first show as a ventriloquist was on radio with Jerry Mahoney in 1943. The program was short-lived, however, as he was overshadowed by Edgar Bergen. Winchell also created Ozwald, a character that resembled Humpty Dumpty. The effect was accomplished by painting eyes and a nose on his chin, then adding a "body" covering the rest of his face, and finally electronically turning the camera image upside down. In 1961, Berwin Novelties introduced a home version of the character that included an Oswald body, creative pencils to draw the eyes and nose and a "magic mirror" that automatically turned a reflection upside down.
