I remember being disappointed that this cover drawing wasn’t used, but I got over it. I penciled this as a possible cover for the first issue of the Mirage-published TMNT color series. This was during a period when I was doing a lot of my penciling in photoblue pencil (the kind that is invisible to stat cameras), because I found it to be physically less messy that regular lead pencils.
The problem was, being photoblue pencil, it was difficult -- if not impossible -- to copy on our Canon copier. I solved this by figuring that if I took a thin sheet of transparent yellow plastic and laid it over the blue pencils, the copier would perceive the pencil lines as green, and thus be able to copy them. It worked! -- PL
