Graf exhibit @ the Brooklyn Museum
This enterprising, and most likely, former tagger, scaled new heights at the Brooklyn Museum to put up his tag. Of course, the tagging was legal. The museum put up a wall where patrons could put up their own tag. What the security staff frowned upon was his scaling of the wall.
A link from the Brooklyn Museum site leads us to the flickr pool of Brooklyn graffiti. Even more interesting is a continuing series of photos on the progression of the mural.
All this was part of the current exhibit on graffiti at the Brooklyn Museum.
