Speak softly, but carry a big can of paint.

The thing I hate the most about advertising is that it attracts all the bright, creative and ambitious young people, leaving us mainly with the slow and self-obsessed to become our artists.. Modern art is a disaster area. Never in the field of human history has so much been used by so many to say so little.

Graffiti is one of the few tools you have if you have almost nothing. And even if you don't come up with a picture to cure world poverty you can make someone smile while they're having a piss.

People say graffiti is ugly, irresponsible and childish... but that's only if it's done properly.

Gray hair is God's graffiti.

In New York -- whose subway trains in particular have been "tattooed" with an energy to put our own rude practitioners to shame -- not an inch of free space is spared except that of advertisements.
