Gerald McBoing-Boing is a 1950 UPA cartoon that won the Academy Award for best animated short. It is about a little boy who communicates through sound effects instead of talking. It was voted one of the 50 greatest cartoons of all time in 1994 by animation professionals. It uses abstraction and caricature in an effort to move away from the Disney style of animation at the time.
