Thurman Munson and Yogi Berra dual signed New York Yankees cap that was most likely used, but cannot confirm who donned it. Signed under brim in blue pen and is a 7 1/2 New Era pro model cap. The cap matches styles and tagging of other 1970s Yankees game caps, which leads us to believe that is is game worn. There is no way to identify who it could have been worn by, but the brim is bent down the middle; which would be consistent with it being used by a player. Comes with PSA LOA for signatures.
