I literally dug through tons of old public domain books and magazines trying to find monsters for speedstar. I found a lot of monsters (I think) but I also found a ton of non-monsters. I thought I should upload the non-monster clipart too. It took awhile to synthesize it all, but I hope it's worth it. This is some sort of Celtic looking graphical element.
