"It was almost like a dry run for me. I had Frankenstein in mind and I wanted to do it. I had an idea what I wanted the drawings to look like; and 'The Muck Monster'—and a few other things I did for Warren—were the embryonic version of the penwork that finally showed up in Frankenstein." - Bernie Wrightson
Very sad to hear about the passing of Bernie Wrightson. In his memory, this was a story he wrote and illustrated for Eerie #68 that would serve as the groundswell for what would arguably be his magnum opus, the illustrated version of Frankenstein.
