Hammering Hank slammed a lot them out of the park but this one was a record breaker the day it was hit. It was number 739 for Aaron, who powered it off the outstanding lefty Vida Blue on June 12, 1975. Spalding official AL ball (Lee MacPhail) is inscribed "#739 - Best Wishes to Joe, Hank Aaron." Joe, is Joe Nossek, who fell just a tad short of Aaron statistically with his 3 career home runs and his .228 career batting average. LOA from Nossek and accompanying wirephoto of Bad Henry rounding the bases after this very blow was struck. Your chance to own a piece of the REAL Home Run King.
