Bill White, center, a former Major League baseball player with the Giants, Cardinals and Phillies, and former president of the National League from 1989 to 1994, listens intently as a fan describes one of his favorite memories during a book-signing event Saturday sponsored by the Philadelphia Athletics Historical Society at the Days Inn in Horsham. White signed copies of his book “Uppity: The Untold Story About the Games People Play,” while Dick Rosen, left, president of the A’s Historical Society, based in Hatboro, looks on. Joining White at the event were two of his former teammates, A’s pitcher Bobby Shantz and Phillies pitcher Curt Simmons.
