Mystic #23

A man wants to go to Jivaro country so he can acquire a shrunken head for his collection of horror memorabilia but is afraid of having his head shrunk, so he hires a scientist to treat his head so that it is unshrinkable. The chief captures him and makes him a deal that if they can't shrink his head, they'll give him one of theirs and let him go. He accepts, and they fail to shrink his head so let him go, but they succeeded in their process with the rest of his body.
