Here's an example with the crescent toning on both sides. Unfortunately, roughly 20 yrs ago, I was organizing my Morgans into plastic rolls but I ran out. Instead of buying more rolls at the time, I used regular mailing envelopes (high sulfur content) to store some. They laid on each other diagonally sort of like this {\\\\\\\}. I just wish I had realized my stupidity before the toning progressed to the final stage of black.
