A pair of single-signed baseballs from two of the greats of their era are offered here. 1) Long-time home run king Hank Aaron has signed this Official National League (Feeney) ball on the sweet spot in 9/10 blue ballpoint ink, with "1974" written above. 2) Lou Brock has signed just to the left of the main stamp on this Official National League (Feeney) ball, in 9/10 blue ballpoint ink. Both signatures are vintage circa 1974, balls are clean and slightly toned to a great cream color, and each retains bold and clear stampings. Aaron remains MLB's all-time RBI leader with 2,297 in his storied career, while Brock's 938 career stolen bases ranks second overall only to Rickey Henderson, though he retains the NL record, having led the league a sparkling eight times.
