Despite becoming well known recently for their conservative political activism, the Koch family has a wide range of interests. Cultural philanthropy, for example. Also, old West memorabilia. One of the lesser-known Kochs, William Koch the Daniel Baldwin of the Koch family purchased a tintype photo of Billy the Kid in an auction over the weekend for $2.3 million. It dates back to 1879 or 1880 and is the only authenticated photo of the outlaw in existence. Mr. The Kid originally paid 25 cents for the photo, so its value has increased a bit over the years.
