Artnet has a few Zev Visual Violation pieces and his work is represented by Lazarides in London.
Not everyone loves visual violations or visual kidnapping. Giorgio Armani was not happy that his Hong Kong boutique became a Zav art installation and took him to court.
Of course there are as many street artists shown in museums and galleries as there are people disturbed by it.
Banksy pieces begin in the low six figures. "If graffiti changed anything it would be illegal" is a Banksy vandalism on a wall.
