Figured this is a good place to put this. Here are all the known examples I can find matched up with their twins.
For most of these there are 2 or 3 examples leading me to think that possibly one sheet may have had 3 of the same player stacked. However I recently confirmed a 4th Doyle (bottom)!
Some of these players should have the Factory 42 over print but do not (likely printed later on in the process), leading me to believe there must have been at least two different sheets printed. Another piece to the puzzle?
