The finest collection of special K-men ever assembled have covered the snow white surface of this Mint ONL (Coleman) baseball with their striking ballpoint signatures. Every one of the eleven specimens belongs to a man who has recorded at least 3,000 strike outs during his major league career. Included are Tom Seaver, Roger Clemens, Bob Gibson, Steve Carlton, Bert Blyleven, Nolan Ryan, Fergie Jenkins, Gaylord Perry, Phil Niekro, Don Sutton, and Randy Johnson. Overall the group grades a near-flawless 9-10/10. Comes with LOA from Bob Gibson and MLB's authenticating hologram.
