The M&M Boys famously battled for the all-time home run title in 1961, and Yankees teammates Mickey Mantle and Roger Maris signed this early 1980s Adirondack bat that features "NY YANKEES" in block lettering on the barrel. Mantle signed in 7/10 blue felt-tip marker, while Maris signed in 8/10 black felt-tip marker. Very seldom does a bat signed by both sluggers come up for sale. In fact, such an item is about 100 times rarer than a baseball signed by the pair. The bat is NRMT and comes with PSA LOA. Swing for the seats and grab up this scarce treasure!
