billy the kid Billy the Kid photo sells for $2.3 million at auctionThe last known image of Billy the Kid sold at a Denver auction on Sunday (June 26) for $2.3 million dollars. (For anyone keeping count, that’s exactly half the amount Marilyn Monroe’s famous “subway dress” sold for earlier this month.)

An infamous Old West outlaw, Billy the Kid — aka William Henry McCarty — is believed to have killed between eight and 22 people during his career of crime. He was relatively unknown during his lifetime until the governor of New Mexico placed a price on his head. But, like many Old West figures, many of the Kid’s exploits were exaggerated.

Billy the Kid reportedly died in 1881 at the hands of sheriff Pat Garrett.

In 2010, New Mexico governor Bill Richardson considered a posthumous pardon for McCarty, but decided against it because of “historical ambiguity.”

Auctioneers estimated that the image would bring in about $400,000, according to ABC News. But the buyer — private collector William Koch — was willing to pay more than $2 million for the image.

“I love the Old West,” Koch tells the Denver Post. “I plan on enjoying it and discreetly sharing it. I think I’ll display it in a few small museums.”
