Unfortunately, there is not much left of the actual Berlin wall, I don't think people thought about the historical significance of the barrier when it came down. In any case, here's a small piece that was on display at the Europa Center. This would have been the west side of the wall, the east side didn't have graffiti as people were unable to get close to it. Photo taken in December 2011. For more murals, take a look at Monday Mural.
