Greg,
Well yes. This made it a little easier. How about "The Dale Avengers." It was painted on the reverse, bled through and painted in reverse, on the obverse. It was too fragile to flip back and forth in the old days so, we had just put it away. Decided to give it one last try only turning once in mylar. Took iPhone shots of both sides and compared the two enlarged views on the computer letter by letter
and clear as a bell, there it was!
