Here's a card from the town of Ferch located on Schwielowsee. Schwielowsee is located south and west of the capital of the state of Brandenburg: Potsdam (and easily accessible with the S-Bahn from Berlin might I add.) The sender mentions this card is from former East Germany, the card even had it's original price printed on it, it costed 0.20 Marks.
So many stamps *_*
The envelope was slightly damaged so Deutsche Post re-sealed it... of course taping over the stamp
