This is true, a partial uncut sheet of PIEDMONT backs was found some years ago. And, I base my contention that the
backs were printed first on that find.

But, you're our resident printer, isn't it common sense that the ONE color process that T206 backs are was printed first ?

Then, the more complex 6-color process in printing the fronts followed....on the pre-printed sheets (with backs) ? ?
