Mailed in 2020 with stamp, postmark, Priority label, and extra sticker affixed.  Seven of the locations are identified, and while we won’t be doing this for every card, we have some time now, so here they are:  Esel am Markt; Standesamt; Lindenbrauerei; am Markt (two of those); Kurpark; and Fußgangerzone.   Grade: 3
