Just noticed something else looking at the two Snider's above.
Check out the small part of Duke's left shoulder under the right edge of the red Dodgers logo and above the R and S in the word Dodgers in the black band on the bottom of the card. Two different sizes of his shoulder are shown.
I just picked out two on ebay. If you run your cursor over the photos posted to enlarge the area you can really see the different size of his shoulder.
