Roughly 30 signatures of the 1960 Washington Senators circle this unused Lenny Green game issued bat. "Washington Senators 1960" is hand written on the barrel in unknown hand, blue ballpoint signatures range 6-8/10 and included is Hall of Famer Harmon Killebrew, in what was to be his final season with the Senators before the franchise moved to become the Minnesota Twins in 1960, just entering the prime of his Hall of Fame career.
