Milky milky

We walked into town today and spent a couple of hours at the museum. They're currently showing pictures, sculptures, film and objects on the theme of bows and arrows. Interesting how many different angles there are: Olympic discipline, hunting, religious imagery, precision, outdoor activity, tension. Before we went into the exhibition, we had a coffee in their seating area. The milk had pictures of German cities on the lids. We identified Berlin, Hamburg and Cologne, but the fourth one (2nd from the left on this picture) eluded us. Answers on a postcard...
