Sports Drawings difference
 

For a while I thought these two cards were the same, but looking closely I noticed that there are a few differences. The card on the left is SGC labeled as a 1920s W542 Sports Drawing Pitcher, but it has the number 10, and the second one is number 12. Also, the border is thicker and darker on the second card, and the cards are framed differently, with the first pitcher's foot nearly touching the edge. Was SGC correct in their labeling, and if so, what is the second card?

The ACC says that the W542's have "10 seen", so its strange the one is numbered "12". ???

size is said to be 1-1/2" X 2-5/8"

I dont know this issue at all, Ive seen the cards but never paid attention.

Maybe try to find a scan of an uncut sheet of this series. Its said to have "#1 Training, #2 Cricket, #3 Tennis, #4 Boxing, #5 Athlete, etc."
It may be there are 2 slightly different sheets of these, maybe one 10 cards and 1 with more, and they just numbered the poses differently. Quite a few strip cards from that Era have variation is the poses and numbering. Even the set(s) most similar to the W542's, ....the W552 "Baseball Position Drawing" has variations in the the designs and colors of some of the players pictured.
