Here is a nice 1948 GPC out of my personal collection of George A. "Iron" Davis who pitched a no-hitter for the 1914 Miracle Braves.
I stand corrected from my initial post. It is amazing that the two players autographs are pretty similar, & I can definitely see how they could be confused.
After seeing Mike's 2 examples of George "Kiddo" Davis, which are identical matches, I believe that your mystery is certainly solved.
Mike, nice job on providing these two examples for the initial poster.
