This headdress is part of the collection of The Buffalo Bill Museum and Grave in Golden, Colorado. It was worn by Chief Sitting Bull in 1885, the only year he participated in Buffalo Bill's Wild West Show. It was treated in 2007 to address several main issues. The object was extremely dirty from years of storage and display. In addition it has some serious structural issues and had undergone previous restoration attempts which were failing. The train had also been previously altered and was missing many of the original eagle feathers, through both neglect and possibly intentional removal. We were fortunate to have access to a collection of historical eagle feathers to use in the restoration, as it is illegal to buy or sell eagle feathers today.
