From above:
The Zaun is an A/B variation and the Cubs cards seemed to have changed logos between the 2nd and 3rd printings. I looked at Beckett again, and the 13 cards that supposedly have only two variations are from a certain group of teams that never include a symbol by the team logo. Taking the remaining 47 cards and removing the known A/B and logo variations (Beckett only mentions the Phillies not the Cubs) leaves the following 22 numbers (if I did my homework right): 2, 3, 7, 8, 12, 13, 17, 28, 29, 31, 32, 35, 36, 37, 40, 42, 44, 50, 52, 55, 58, 60.
Because of what I have seen with the Carews, I would assume these 22 numbers do not have a 3rd version (below scarf and missing by logo). Has anyone found 3 versions of any of the listed numbers?
