Here's a letter dated May 19, 1914 signed by
Chief Meyers on the day he caught
Christy Mathewson's 342nd career win.
The Native American from the Cahuilla culture writes, “In the game today, with the Cincinnati club with Mathewson pitching, I used the Model C.M. Catcher’s Mitt, made for me by your firm yesterday."
The rest of the letter is worth reading too. This letter and many other autographs can be found on CooperstownExpert.com, a site that has pages for every Hall of Famer and more than 250 other baseball men.
Hope you can enjoy it.
