The hair is said to have been originally obtained from Martha Washington's side of the family and passed through generations. It was acquired by Topps via the collection of noted hair and autograph collector John Reznikoff. It may sound strange, but collecting hair from famous people was fairly common in the 18th and 19th centuries.UPDATE: Apparently the original auction was pulled for not complying to some unknown eBay rule. Have no fear though, it has returned. Check out the new auction here.
