Monster Blood

While I finish work on a bigger AEET post (coming this weekend hopefully!) here's a neat little mail order monster ad from a 70's Marvel comic. It's not enough to just get some disappearing blood to fool your friends and family with, but you get FREE fangs to go with it too-- yay!! Does anyone know anything about Salt Lake City's Prof. Prank's Lab? A quick search online didn't produce a single result, but surely they had other cool junk like this as well. Man, I love the way the Prof is illustrated-- and would've bought tons of stuff from him just because so!
