On Tuesday I got a postcard from Germany.
It shows the Kunsthalle Hamburg. The Kunsthalle Hamburg is one of the largest art museums in Germany and shows European art from the Middle Ages to the present day. It was founded in 1850. One of the most famous artworks in its collection is Caspar David Friedrich's Wanderer above the Sea of Fog and The Sea of Ice.
