From 1933, here's Willie Whopper starring in his first cartoon, "Air Race, " in which tells this fantastic yarn about himself participating in an airplane race.  This cartoon, produced in Los Angeles by Ub Iwerks at his cartoon studio, was released theatrically by Metro-Goldwyn-Mayer.  The reason for the header can be found at 4:46 of this video.  After two cartoons, as was the case with another Iwerks star Flip the Frog, Willie would be redesigned, transformed into a freckle-faced, roly-poly redhead.
