Back in the early days of the TMNT comic book, Kevin Eastman and I would alternate cover duties. He did the artwork for the cover to the first issue (although, if memory serves, I did the mechanical color separation overlay for the red color on that cover), I did the second, he did the third, and so on.
This is my cover drawing for TMNT #2, done on the duo shade board we used for the interior art. I’ve reproduced this black and white art in color to show the sepia tones created by the aging toning chemicals in the paper.
I think this was the first time I tried using the toning chemicals in my airbrush -- boy, did that dark tone chemical stink! It was truly vile. -- PL
