A shrunken head is a severed and specially prepared human head that is used for trophy, ritual, or trade purposes.Headhunting occurred in many regions of the world. But the practice of headshrinking has only ever been recorded in the northwestern region of the Amazon rain forest. [from Wikipedia]
I had always thought that shrunken heads were fake until I visited the world’s largest collection at Ripley’s Believe It Or Not in Manhattan. I later found out of a book called Head Hunters of the Amazon: My Adventures In The Jungle 1894-1901 which is now on my future reading list.
