I've seen this listing before, but I'm almost positive that it's incorrect:

George "High pockets" Kelly (no "e" before the "y") was the 1st Basemen... not a pitcher. He did make the HOF, but that pic is not him... but this card is listed as "M. Kelley" on the Giants... I've checked the roster for the 1919 and 1920 New York Giants and I don't see a pitcher named "M. Kelley" in there.
I'm guessing there must have been, though. Can anyone clear this up?
