Here's another water tower photo. I helped with this one. It looks a little different now, there have been many yellow peace signs added to it by the original artist, DF Paul. I never answered td's question, I think it was td. The big murals like this one aren't painted over, the real graffiti art, some of which is really good, is painted over and they do it again. At some point I expect that everything not an official mural will be painted over.
