An old, but recently discovered photo shows two men standing together in what historians figure must be about 1879, and there’s new evidence that the man on the right is none other than Billy the Kid..

If true, it would be only the second known image of the Wild West gunslinger. The other one has already fetched millions of dollars at auction.

New Mexico historian Frank Parrish, of Las Cruces, revealed the new image, made from a tintype owned by a Mesilla Valley man who wishes to remain anonymous. And Parrish has done some extensive research to back up his claim that the man on the right is the legendary gunfighter who was also known as William Henry McCarty Jr., William Bonney and Henry Antrim. Much of it is based on identifying the man on the left, as Dan Dedrick.
