Off white C.Feeney National League baseball which was used in the historic game played on August 29, 1977 in which Brock eclipsed Ty Cobb's all time stolen base record. The ball stampings and surface appear to have been rubbed up a bit to allow for the tastefully executed stenciled decoration often seen on Cardinals' milestone baseballs of the era. Brock set the new mark of 893 stolen bases to move past Cobb two years to the date which he hit the 800 steal mark. The stolen base record was one which many within the game believed would never be broken and yet both Lou Brock and subsequently Rickey Henderson would each do so in the modern era. The ball originated from the personal collection of Lou Brock. Includes letter of provenance signed by Lou Brock: NM
