This may be a photo of Billy the Kid, Doc Holliday, Jesse James, and Charlie Bowdre, taken in Las Vegas (NM) in 1879:
“There is that story that these two met in Las Vegas at the Old Adobe Hotel on July 26, 1879, and during a card game Jesse asked Billy to join his gang……….Henry Hoyt and Migeul Otero say so in their books, and that they witnessed it…………..But Jesse James did stay at the Old Adobe Hotel from July 26 through July 29 in the summer of 1879, according to an announcement in the Las Vegas Optic printed weeks later. The owner of the Old Adobe Hotel, W. Scott Moore, was from Clay County, Missouri, Jesse’s home turf, and was a childhood friend of his. Hoyt recalled Jesse’s missing finger and his alias, Mr. Howard. And Jesse was on the run, so New Mexico is possible.”
