"Big Bull" (aka "Hornaday's Bull") is the buffalo that the United States Treasury Department used as a model for its Buffalo Nickel. William T. Hornaday killed and stuffed Big Bull in 1886 because he wanted something to remember the wild buffalo by that were becoming increasing small in numbers due to the settlers out West overhunting them. Big Bull was then shipped to the Smithsonian Institute where the Treasury Department discovered him. They used Big Bull as the model for stamps and nickels. In 1970, the town of Fort Benton brought Big Bull back home & put him on display at the Museum of the Upper Missouri, which is where he remains today.
