1904 Butch Cassidy and Sundance Kid $2,000 reward poster or flyer from Pinkerton's National Detective Agency Circular (No. 3, Denver, Colo., November 14th, 1904). Pinkerton's Circular issued this two-page reward flyer after the robbery of the First National Bank of Winnemucca, Nevada on September 19th, 1900, during which $32,640 was stolen. The poster features photographs of George Parker, alias "Butch" Cassidy and Harry Longbaugh, alias "The Sundance Kid". Adhered to back are two other reward flyers, one for a stolen mule and the other for a stolen red bay horse. 11" H x 16 3/4" W. Note: prior to the establishment of the Federal Bureau of Investigation, it often fell to private companies to arrest suspects across jurisdictional boundaries. The Pinkerton National Detective Agency, founded in 1850, was one of the country's most important such companies and it issued a circular, alerting local lawmen to information about wanted fugitives. For additional information on the agency and similar examples, see "Wanted! Wanted Posters of The Old West" by Barbara Fifer and Martin Kidston. Provenance: collection of a former Knox County Sheriff. Condition: Overall toning due to acidic paper backing of the scrap book. Folds and creases, laid down. Some water damage evident to lower margin.
