This rare piece of memorabilia contains the autographs of baseball legends Willie Mays and Bobby Thomson on a vintage Official National League baseball (Ford Frick) from decades past. This game-used baseball was signed between the seams in blue pen (8/10) by Mays and on the panel below in (7/10) blue pen by Thomson. The Thomson signature could be from the 1950's, but the Mays is later (probably 1970's).
