A comment on graffiti removal, perhaps?

Bus stop, near Gyllyngvase Beach, Spernen Wyn Road, Falmouth, 8/4/08.

I quite like this bit of graffiti. Sure, it's a cliché, but even clichés can be meaningful in the right context. Here, for instance, it's just not what you'd normally expect, either from graffiti, or the side of a bus shelter. Usually, there'd just be some advert calling upon you to think nothing more reflective than "Must consume", "Run Fat Boy Run," or "Jordan's written a children's book about ponies? Well, I'm sure that'll be marvellous. And doesn't at all make me despair for the future of the human race."
