For this comprehensive revision of his earlier biography of Wild Bill the author was allowed to work from newly available materials in the possession of the Hickok family. He also discovered new material pertaining to Wild Bill's Civil War exploits and his service as a marshal and found the pardon file of his murderer, John McCall. Additional, rare photographs of Wild Bill are published here for the first time. The results of Rosa's additional research make this second edition the best biography of Wild Bill likely to be written for years to come.
