Reznikoff has pieces from Marilyn Monroe, Napoleon, Albert Einstein and even Abe Lincoln, complete with chunks of brain matter from his assassination. Hell, he even has some hair from the man who shot him (Wilkes Booth got clipped while being dragged from his burning barn hideout).
So how do the still-living celebrities feel about this? Well, in 2005 Reznikoff struck a deal with Neil Armstrong's barber on some snippets, but when Armstrong heard of the transaction he tried to block it. His efforts failed, and Reznikoff donated several thousand dollars to his favorite charities as a consolation. Money he'll surely make back when he clones his spaceman army).
