I got this card which has been signed and stamped by a few different people who attended a Postcrossing meet up. The sad thing is that it doesn't have much of a message on the back. I know that some people like getting a meet up card, based on this one, I'm not one of those people.
On the back it says, "Hi, greetings from the Postcrossing Cologne Meetup! Nadine"
I should say that I like the picture on the postcard.
