This is a Louisville Slugger model D29 Joe DiMaggio professional model bat measuring 34" in length and weighing 36.3 oz. Due to conflicting information on the two LOAs pertaining to this bat, it is either from the 1950-51 New York Yankees ordering period (per GameUsedBat.com LOA), or the 1955-1957 labeling period (per PSA LOA), which occurred after DiMaggio had retired as a professional ballplayer but during the years he worked as a batting instructor for the Yankees. In any event, all sources concur that this bat was game used by a member of the New York Yankees, and could, in fact, have been used by Joltin' Joe himself. The bat has a small chip in the knob. Comes with both LOAs.
