A new stamp for my collection

I received my new driver's license in the mail today (my other one was in my car....), and I noticed that there were stamps on the envelope. You may think that stamps on an envelope are normal, but around here, my letters usually get run through the machine, because my post office doesn't have stamps. I looked closer and saw the mitre on the stamp and thought, "Hey, a pope stamp." Since the current pope was just here, I thought that was a good commemoration. Upon looking more closely, I realized that it wasn't the current pope on the stamp. It was the latest dead pope.
