Henry McCarty, known in Wild West lore as Billy the Kid.
In a surprising historical twist, the second photo of McCarty ever to be authenticated shows him and his posse, the Regulators, playing the sport in New Mexico in 1878. The faded image was among a pile of photos inside a cardboard box at a junk shop in Fresno, California, unearthed by a collector in 2010. Randy Guijarro paid $2 (£1.30) for the image, which is now estimated to be worth millions of dollars. The only other confirmed photo of Billy the Kid, from 1880, sold for $2.3m (£1.5m) in 2011. The photo was authenticated by a San Francisco-based Americana company, Kagin’s, which identified Billy the Kid along with several members of the Regulators, as well as friends and family. It was taken after a wedding in the summer of 1878, just a month after the gang took part in the brutal Lincoln County war.
