The Only Known Win Clark Single Signed Baseball. Clark was a member of the 1897 Louisville Colonels and went on to be a successful player/manager in the minor leagues but is most widely recognized for his role as Secretary for the Association of Professional Ball Players of America (APBPA). Clark passed away in 1959 and his signature is considered scarce in any variation. This is the only Win Clark single signed ball that is known to exist. The blue ballpoint signature rates approximately 9/10 in strength and is dated “5-18-1955” in Clark’s hand. The ball is in near mint condition with a light tone throughout. Sadly, Clark lost both of his legs to diabetes and spent the last years of his life in a wheelchair. Upon hearing of his death Walter O’Malley said, ““Win Clark’s grand contribution to baseball and many of its less fortunate players would be difficult to measure and to match. In the face of tremendous personal handicap, Win spent all of his time and efforts making the lives of others more comfortable and happier. He was unique to our game of baseball.” Includes a Full Letter of Authenticity from JSA (#BB11976).
