Germany: Bielefeld Postcrossing Meet-up

On Wednesday I got six postcards: two from Germany, one from Hong Kong, one from the United Kingdom, one from Japan and one from Indonesia

One of the cards from Germany shows a stack of postcards.

The card was sent from the Postcrossing Meet-up in Bielefeld.
Stamp:
Dresden (from set of two) (issued 03-04-2014)

Thank You very much Sabine!
