The T206 Ewing thread got me thinking about some of my Weil Baking cards. If you look at a "normal" back, the "a" in action is fine. The first scan shows a normal "a".
If you look at the next two scans, there is what appears to be a comma in front of the "a", and the last scan shows part of the "a" is missing.
I find it kinda of interesting. That goes to show you how exciting my life is, when I am finding minor printing flaws on the backs of cards.
