A trio of popular Hall of Famers make their marks, with these (3) single-signed 1974-1976 OAL/MacPhail baseballs. These period-signed balls are all autographed on the sweet spot, with: Hank Aaron: signature ("5"), ball (VG); Rod Carew: signature ("7"), ball (EX); and Harmon Killebrew: signature ("7.5"), ball (EX). The following is cited on the Carew LOA, "Apparently, the initial blue ballpoint stroke of the "R" was abandoned for a more reliable blue ballpoint pen." Each autograph comes with an individual full LOA from James Spence/JSA.
