As the sign reads:
Genuine European Shrunken Head
Believe It or Not! this head came from a normal sized person and is believed to be the only red-haired European shrunken head in the world.
To shrink a head, the Jivaros slit the back of the neck and peel the skin away from the skull. Once the skull is removed, they sew the head, including the eyes and mouth, back together. Hot stones and sand are poured into the vacant cavity and the head is boiled in a broth of secret herbs. Finally, the miniaturized head is cured over an open fire to give it a distinctive leathery texture.
