John Reznikoff is one of the foremost autograph and ephemera dealers in the world. So when he decided he wanted to start collecting something, he wanted to pursue something that wouldn't be a conflict of interest. So he ended up collecting hair.

John owns the locks of Abraham Lincoln, John Wilkes Booth and Edgar Allan Poe, among others. We talked with John about his collection and how he authenticates something as personal as follicles. For more information on John's collection or to see what cool things he's auctioning off now, check out his company, University Archives.
