Here are two drawings from the VERY early days of the TMNT, quite possibly drawn before the first book was printed. I drew these on some of those scraps of Graphix Duo-Shade we had left over from cutting the page-sized sheets out of the big sheets of Duo-Shade board (we used every little piece of that stuff!).
It's interesting to look at drawings like this to see how the way we drew the Turtles changed drastically from those early days. -- PL
