Minus the City

So i read about something very green happening in San Fransisco recently. It may not be enough to reverse everything we've done to the world but it makes a pretty good point and as a new take on Graffiti art it takes away from a city what we've been layering onto it for decades. Check out these British Graff Artists and their Reverse-Graffiti
