No fewer than 22 greats signed this official National League (Feeney) baseball after their playing days were long over. The standout signature is a beautiful "Lefty Grove" alone on the sweet spot, and he is joined on the cowhide with contemporaries such as Blackwell, Kluszewski, Gilliam, Bell, Slaughter, Post, Mize, Irwin and more. The signatures average 8/10 and the ball is in NRMT condition. The autographs were obtained during the mid-1970s, and the Campanella is a clubhouse version.
