The greater majority of T206 Subjects (187) in the 350 Series have been confirmed with the American Beauty 350-Frame back (ABF).
There are 27 subjects that have yet to be confirmed. There is a 99 % certainty that 17 of these 27 were not printed with the ABF
back due to trades, retirements, or Minor Lge. reassignment....when the ABF cards were being printed (circa Summer of 1910).

Thanks to an avid reader of Net54 for confirming Warhop with an ABF back.
And, thanks for your time and effort in tracking down any of these 10 remaining T206's with the ABF back.
Or, try to prove the experts wrong, by discovering any one of the above 17 "NO-PRINT" Subjects with an ABF back.
I was expecting several more by now that would have been reported.....but, this is still a good start. After all........

....only THE MONSTER's SHADOW knows....
Perhaps, there may be as many as 27 American Beauty 350 frame "NO-PRINTS" in this series ? ?
