Graffiti - art or vandalism? It was the cavemen who started it a long, long time ago.
Then the Egytpians came along scratching all over the place, followed by the Romans carving their names on walls and monuments. Even the Vikings had a go until eventually the subways of America, and many other places were covered in 'masterpieces'.
One such masterpiece now adorns this page - a graffiti puzzle for you to gaze at and ponder.
