during our recent trip to nyc, we happened to come across some street art pranks by paul richard. paul creates small signs, the same kind you would find describing an artwork in a museum, and attaches them to objects on the streets. his other creation are 'dripped portraits' to be found on pavements, like the ones u can see here on flickr. one of his last 'interactions' was a sign asking not to tag sheparf fairey's mural. unfortunately in vain...
