Probably a question for Ted and Scot, but does this card tell us anything certain about the timing of the T206 production process? It is obvious that the back is a Piedmont 350 (you can see the bottom of the "3" in the upper right corner), but there's nothing that indicates this card could not have been part of a blank-backed sheet left over from the 150 subjects printing, and used as a test sheet for both 150 printing and later 350 printing tests.
