This 1956 Charleston Senators team signed baseball was acquired from the Charlie Lau collection. It was signed by 17 members of the team including Lau, and very tough autograph, Duke Maas.
Maas was a part of the Yankees 1958 World Series Championship team, having previously been in the Tigers and Athletics organizations. Maas passed away in 1976 at the age of 47 and is among the most difficult Yankee autographs to obtain.
