I walk by 520 Madison Ave in NYC all the time, this is the first time I noticed this huge piece of a graffiti wall - it's an actual piece of the Berlin Wall. Incredible, that it's been there for a long time and this is the first time I noticed it. If you want to go to take a look for yourself it's right around the corner from the Thomas Pink store you can't miss it. (Keep your eyes open, if you walk around haphazardly like I do you might miss it.)
