No. 193 - arriving mail art from me (Germany) - the experiment worked so far that it came back (see below) but the post office noticed the faked postage stamp and stamped "Postwertzeichen ungültig" (non valid postage stamp) next to it another special postal stamp "Nachträglich entwertet" which means canceled afterwards. So the head of Bismarck has been canceled, thats funny. In between the handwriting with blue editing pen "96", the taxe rate to pay, but I do not have to pay anything. It's fun and I will try it again next time. Maybe try it as well.
