One of its early products was a wind-up toy featuring two tin boxers.
The company scored a hit in the 1940s when it acquired the rights to a popular comic strip and released the Li'l Abner Dogpatch Band for Christmas 1945.
Marx saw this as a betrayal and responded with a new line similar in size to Unique's, but with lithographed rolling stock that looked more realistic.
Marx responded by moving production of its typewriter toy to Japan in order to undercut Unique's price.
The circumstances surrounding Unique Art's eventual demise is unclear, but the company appears to have disappeared in 1952, when it was picked up in a corporate merger by the Jerry O'Mahony Diner Company, with some evidence of Marx picking up parts of the line.
