The ball actually dates to 1940-46.
I have compared this autograph in hand to Ruth exemplars (autographfacts) and I believe it to be authentic.
"1940-1946 Ford Frick Spalding Official National League Baseball"
Can I please get some more opinions on the autograph? I think I want to take a shot on this one.
