Louisville Slugger 125 model hickory bat with striking eye appeal measures 35 1/4" long and weighs 34.9oz. The bat shows evidence of strong use to include ball marks, stitching impressions cleat marks, and a repair to slender handle crack. Both manufacturer centerbrand and Gehrig facsimile signature stamp present very boldly with outstanding contrast. Most notably, an area of the back of the barrel displays the trademark Hllerich & Bradsby factory side writing as executed upon the return of a game used bat for player order. Partially faded to history, but mostly legible under light enhancement, period grease pencil notations, "Tony La---ri 6-13-29" are found on the planed area of the barrel . The side writing amazingly confirms that not only did Lou Gehrig utilize the offered hickory weapon but dually his Murderer's Row teammate Tony Lazzeri. This dual use can be confirmed not only by the Gehrig stamping and Lazzeri side writing but distinct corroborative usage characteristics for both players. Indicative use including ball marks, stitching impressions, and scoring is present for both left and right handed players as succinctly listed within the PSA/DNA letter. Lazzeri later ordered this exact Gehrig model bat with his own branded signature stamp further attesting to the lineage of Lazzeri trying and adopting Gehrig's bat type. The Iron Horse terrified and humbled American League pitchers between 1925 and 1939 with consistent and relentless power in a truly unprecedented form. Gehrig won the American League MVP Award twice, led the American League in Home Runs three times, led the American League in RBIs 5 times, 1934 American League Batting champion, 1934 Triple Crown award winner, 7 time American League All-Star, and 6 Time World Champion. The specific 1927 order date for this bat places it in Gehrig's hand during his most historic season. Incredible baseball equipment artifact with relation to two iconic Yankee Sluggers of the vaunted 1920s era. Includes LOA from PSA/DNA (GU 8): EX
