We are mostly familiar with the more popular Disney and Warner Brothers animation shorts, or Max Fleischer's Popeye, however I found these U.P.A.(United Productions of America) cartoons have a unique look that sets them apart. I would say their style is more design orientated, many parts of them cross over into graphic design, with limited color palettes and simple backgrounds.

The inventive use of limited animation is really wonderful even if the scripts are not fantastic and is probably why they are less well known.
