No COA, but you can just tell this is the real deal. Looks to have 33 signatures in total. Com, there were 32 players on the roster in 1981.
The 33rd signature must be that of the manager, Ralph Houk. His signature appears to be right under Carl Yastrzemskis. That said, Im assuming this ball is signed by the entire team, but I havent actually checked. Hopefully the pictures speak for themselves. Feel free to message me with any questions and Ill do my best to answer them.
