Billy the Kid? – How the notorious Wild West outlaw is still a “wanted” man, and why everyone—even National Geographic—is interested in getting to the bottom of the authenticity of his image

A family photograph, long rumored to feature the wild western outlaw, Billy the Kid, is brought to the set of GBH’s Antiques Roadshow in 2017 where it is quickly and roundly declared as inauthentic. In fact, there is still only one truly authenticated image of “the Kid” known, although countless more have made the claim—some with more plausibility than others. But why does Billy the Kid’s image remain so sought after and so notoriously rare? Host Adam Monahan digs into the case, and along the way discovers a story about the limits of technology, the value of historical accuracy, and the power of belief.
