Meetup card from Cologne, Germany

On October 19, I'm hosting the first Calgary Postcrossing Meetup. I've designed a special card for it. Mieke from Germany swapped me this card from a meeting in Cologne. Very pretty, and I had not realized that some Postcrossers use stickers or rubber stamps to "sign" the back of cards. I should look into that before our own meetup, because the group is going to be signing a lot of cards!
