From the BBC Washington office comes this amazing photo. It's not been photoshopped, but it just might be a photo that includes Wyatt Earp, Butch Cassidy, the Sundance Kid, Teddy Roosevelt and Judge Roy Bean, among others.
If it is real, it is extraordinary: a moment when the myths and legends of the Old West crystallised for a moment into a single group photograph before evaporating again into the anonymity of the hot afternoon.
The story is told that the 15 men include Butch Cassidy and the Sundance Kid, Wyatt Earp, his brother Virgil and their friends Doc Holliday and Bat Masterson. The lounging figure is - or might be - Judge Roy Bean, who conducted trials in the bar of the saloon he owned in Texas and encouraged jurors to buy drinks between cases. A few feet away, apparently on an upturned crate, sits a figure identified as Theodore Roosevelt, the future president.
The picture is genuine in the sense that it is a real photograph of 15 men from the 1880s. Just can't be quite sure who they all were.
Teddy Roosevelt did retreat into the western wilderness in 1883 after the death of his first wife and when Butch Cassidy, Wyatt Earp, Doc Holliday and Bat Masterson were all dotted somewhere around America's ragged and dangerous western frontier.
