Graffiti on buildings and other objects is considered a crime of vandalism, and in most cases I agree completely. On the other hand, some of the most interesting urban scenes contain graffiti, and I think it can occasionally cross the boundary into the art world, worthy of being seen and not hidden or removed. I found these two images on one of my recent outings, quite unexpectedly. They are hidden from view, except if you are crawling around under bridges, but I find them quite striking.
