In this Friday, Oct. 19, 2012 photo, memorabilia collector Ken Kallin poses with a copy of his autographed Nelson Mandela book from his collection in Oakland Park, Fla. Three decades ago, Kallin began amassing 120,000 pieces in a memorabilia collection that includes photographs signed by Muhammad Ali and Neil Armstrong along with rare books and trading cards. By the end of Saturday, Oct. 27, 2012 he's hoping to have gotten rid of nearly all of it _ at an auction to benefit his daughter, who suffers from a rare autoimmune disease that makes her bones dangerously brittle and causes her body's defenses to attack her own blood vessels.
