One of the many Krazy Kat cartoons to be colorized by Fred Ladd's Color System Inc and International Arts Production in South Korea for Columbia Pictures sometime in the 70's.
Most people believe that only 18 Krazy Kat's were colorized but in reality there were actually more that were colorized then just 18, though they are a lot harder to come by these day since they were only released for theaters and home movie release but never shown on television.
The one you see here is the theater re-release of the cartoon which originated from a 16mm but blown up on to a 35mm film.
It's also available on YouTube too! https://www.youtube.com/watch?v=JT2YyCZssbw
