Over the years, I have tried -- generally successfully -- to save a copy of everything I've drawn. Sometimes they are just tiny scraps of paper with tiny, scribbly drawings on them, drawings that most people would probably just chuck in the wastebasket (and rightfully so). But every so often I run across something that reminds me of the process that one goes through in creating a drawing for, say, a comic book cover.
Case in point -- I saved this little piece of paper with three of my small and VERY rough "thumbnails" for three covers for the Archie "TMNT Adventures" book -- from left to right, #'s 42, 44 and 43. (In fact, I think these drawings may literally be about the size of my thumbnail!)
I thought it would be fun to show those thumbnails and then the finished pencil drawings that they eventually evolved into. -- PL
