Joshua,
You said "I have seen only one other "Crack Batteries" cover (Bender and Thomas)and have heard of a Matty cover but have never seen it."
I have seen the Matty Cracked Batteries cover, probably three years ago now. I was the underbidder on Ebay. If memory serves it was Mathewson paired with Benny Kauff, which would date it to 1916 at the earliest.
