I recently participated in this online project.. I was stoked to get this opportunity because the classic version of the Marvel Handbook was my gateway into comics and it was the time that I began to take drawing seriously. I copied so many of the drawings from this handbook as a practice.
I think I was a pretty good copier at the time too. Here are my versions of characters based from entries in the original hand book. Or you can go here and view them at the OHOTMU site.
