This is the black and white drawing Kevin Eastman did as the basis for a finished color piece that was used on the cover of the second TMNT role-playing game book published by Palladium Books back in the 1980's. I believe the title was "Teenage Mutant Ninja Turtles Adventures".
I think this is one of Kevin's best cover layout designs, and the color version was very cool. But I always found the Foot ninja in the skirt (in the foreground on the left side) kind of odd. -- PL
