Need quick answer on Gehrig Postcard/Exhibit

[BeanTown]

So, the Cobb listed in the gallery most likely is a 1925 example. So, what year would you guess is the blank back portrait Gehrig? I’m guessing it’s 1925/26 and seeing a pop of 3 compared to the more common postcard back I’m assuming it’s early in the run. Is it common to have different leagues like “A.L.” and “A.M.” all from the same year &series.

I would not definitively state that the blue-green Gehrig is a 1925 printing; still too speculative for my tastes. Woody Scharf was pretty adamant that the 1925 cards were black and white and I think he has that correct. A Detroit Cobb could be 1925 or 1926; he was forced out of Detroit in November 1926. I suspect that it is one of the black and white 1925s if blank backed. The Gehrig portrait itself is a 1925 Conlin image, so that doesn't help.
