This is a fun project: What you can only barely see here is in fact a banner running over the length of one kilometer along the track of the Berlin Marathon. I wrote the copy for it - it is the history of the Marathon in Berlin. But there's more – we handed out postcards to spectators waiting for the runners and gave them a task: "Find these four facts and win a yearly subscription." So off they went reading the whole banner. This ambient stunt and the entire campaign won multiple outdoor awards.
