Cal Ripken Jr. autographed this Wilson Official International League baseball before he was called up to the Orioles in 1981. The rest is 2,652 consecutive games of history. Ripken's signature on the game-used sphere is above the stamp of league President Harold Cooper and a real stand-out amongst the 22 other signatures penned by his minor league teammates - Doc Edwards (Mgr.), Dan Logan, Tom Eaton, Dallas Williams, Nate Snell, Brooks Carey, Tommy Rowe, etc. NRMT signatures with appropriate evidence of game use on the hide.
