I must have read this at least 10 times in my youth. Unlike later Believe it or Not Books, this one contains a lot of text as well as pictures. I believe this is where I first read about the awful Aztec sacrifices and my all time favorite--the Crystal Skull of Doom, which I will NEVER mock. If you see a copy of this one, grab it. It will give you some fun (and a few creepy) hours. ( )
