(DENVER) -- One of the last surviving images of Billy the Kid fetched more than $2 million at an auction in Denver this weekend.
The unnamed winning bidder forked over $2.3 million to take home the tintype image of the 19th century bandit, whose real name was William Henry McCarty.
Auction organizers originally estimated the picture would bring in about $300,000 to $400,000.
The photo shows Billy the Kid wearing a black hat and holding a Winchester rifle with a holstered Colt pistol on his hip. The snapshot is believed to have been taken in Fort Sumner, New Mexico during 1879 or 1880 -- before he began his gunslinging career in which he killed anywhere from eight to 22 people, according to legend.
It is reportedly the only authenticated, surviving image of the outlaw.
