50 years ago this week, a wall started going up in Berlin. The wall was “permanent” and the city was divided. And then, in less than 30 years, the wall came down. Of course, there is much more to the story of the Berlin Wall, but one of the ideas I always take from it is that the lines we put on maps are never permanent. I have a pile of atlases that I recycle for my art. It did not take long to find four maps of Berlin for this piece. Before World War II, post-war, then divided with West Berlin like an island and finally a modern map showing the German capital.
