When collector Randy Guijarro bought some old photos back in 2010, one in particular stood out to him: a black-and-white picture of people playing croquet in the country side. He had no idea, however, just how significant that photo was. Americana expert Kagin’s Inc. recently confirmed that the people featured in the photo are none other than legendary outlaw Billy the Kid and his gang of Regulators.

The best part about this story is that Guijarro bought the photo because he liked the way it looked, which is the most important thing when it comes to antiques. Get a closer look at the photo, and hear more about Guijarro’s historic find, in the following news clip from KOAT.
