Yeah! This round I am one of the early ones. That never happened before. All that is needed is stamps. My cards will go to the post office today and hopefully arrive in good condition in your mailbox soon.
Edit: And when I arrived back from buying stamps I saw the postman leaving and found the first round 27 postcard in my mailbox. And the winner for this round is - surprise surprise - piu58 with a nice print of of a statue of Gottfried Wilhelm Leibniz in front of a former University building. I like the point of view you took for this and as always perfect execution. Thanks!
