This is a ARC Captain Clone Wars Character Key Cel from Acme Archives. A character key is used by animators to match colors during the painting of animation cels. The image here is printed on a clear cel and floats above the background image. This cel shows the red ARC Captain clone trooper as he appeared in the Clone Wars Micro-Series on Cartoon Network. It is a limited edition key and is numbered 513 of 750 and is another amazing piece of the Acme Archives Clone Wars line.
