Experts now believe a photo purchased at a flea market for $10 shows Billy the Kid standing with the lawman who killed him, making the snapshot potentially worth millions.

Frank Abrams, a North Carolina attorney, first spotted the tintype photo in Asheville in 2011.

After seeing a TV program in 2015 about the discovery of a photo of the outlaw playing croquet, Abrams was inspired to research him further. Thats when he thought he recognized Pat Garrett, Billy the Kids former friend and the sheriff who gunned him down.

A Los Angeles forensic video expert said facial recognition software indicates that it is most likely Garrett and Billy the Kid in the picture, according to a signed declaration.

A handwriting expert in Texas declared the handwriting on the photo a match to Garrett.
