I recently visited the Museum for Contemporary Art at the Hamburger Bahnhof. Unfortunately, the museum (like many here in Berlin) is undergoing renovations and parts of the collection were not on display. I did however enjoy seeing some of the works of Joseph Beuys. Bueys was a masterful sculptor, but he is mainly remembered for his later works of performance art. These chalkboards are what remains of a performance entitled Directional Forces of a New Society. It was quite an interesting piece, I'm sure it was even more so at the original event. For more signs, visit Signs, Signs.
