These were a blast. A comic site was raising money for the comic book legal defense fund (aka CBLDF or those badass defenders of the first amendment). They did so by selling original sketches of monsters on ebay.
And get this, I got an email from the guy who bought one of mine saying how happy he was with it! Turns out it was the Book Burning Boiler.
This is evidence that I need to do more fun pinup work.
