 The artist's reference file for the sculpture included a photograph of a cowboy that very closely resembled his 1892 illustration of "A Bucking Bronco".The "Bronco Buster" followed the same kind of process liberating horse and man from two-dimensionality as before.On September 13, 1898 at Camp Wickoff at Montauk Point, New York, the Rough Riders gave Theodore Roosevelt a casting of "The Bronco Buster".
