Here is an image of a Native American pipe stem circa 1800 - 1825. It features an Ivory-billed Woodpecker scalp that is apparent to the far right, in black and red, just to the left of the two blue bands that are separated by a brown band. The pipe belongs to the Peabody Museum of Archaeology and Ecology at Harvard University. It was loaned out to the Metropolitan Museum of Art in New York City as part of a beautiful exhibit entitled The Plains Indians - Artists of Earth and Sky, at the museum, March 9 - May 10, 2015.
The book that accompanies this exhibit explains:
"Attached to the stem is the head and scalp of an ivory-billed woodpecker, a bird widely associated with leadership, warfare, and calumet ceremonialism."
