Honestly. Quality control across the board at many of these places is simply not up to par. Take a look at the autograph they purport to be Mordecai Brown. First of all it looks nothing like a Mordecai Brown signature. Secondly, it isn't "M Brown" but rather "W Brown" which means that it is Walter "Jumbo" Brown. Also from the signatures that they cannot discern I can see Tony Lazzeri, Herb Pennock, and notably Hank Johnson. His presence as well as Jumbo Brown makes this a 1932 Yankee partial ball.
Mordecai Brown? Really?
