☩ I had a very poor quality photograph, it's caption saying that the object depicted is a Cheyenne war bonnet from circa 60s to the 70s of the 19th century. The details were not visible, the feathers were dirty and torn, but it's overall color scheme, which was a combo of dark-green and blue colors, and the presence of a short trailer, seemed to me very significant (and for good reason, because green is the color of Earth, and blue is the color of the Sky, the Thunderbird and other celestial entities). The rest had to be thought up on the basis of this context and is out of my head. Therefore, this replica bonnet is not an exact copy, but a work «based on». Moreover, an exact copy can not be made even by the contemporay Indians themselves, because nowadays no one knows exactly what the earlly headdresses actually looked like, and most importantly, what kind of symbolism their makers intended for them, was any given bonnet a regalia of a particular military society (society bonnet) or it was a so-called personal medicine headdress. And this determines the set of specific materials which it was actually made of.

☩ Also I should add that Northern Plains style Feather War Bonnet with a Short Trailer is a premium-class bonnet made by me in 2017 in a period-correct fashion and using authentic materials. The overall finish and attention to details renders this bonnet a completely believable replica and looks very good to me. Note the pictures and see if you agree. The feathers for this bonnet were collected over several years and then carefully selected by color, shape and size.
