All are different and from the personal collection of Lou Brock, who tirelessly obtained each of these signatures in person. The postcards themselves are mostly NRMT while the signatures average 8/10 condition-wise. To name a few: Brett, Dandridge, Doby, Drysdale, Hunter, R. Jackson, Killebrew, Mathews, Mays, Mize, Musial, Reese, Schmidt, Spahn, Stargell and Yaz. These specimens will delight for decades.
