“Such antagonism goads people, as it is designed to. For a while, the Wikipedia entry for Banksy began, “Banksy is a nancy boy. Banksy is a rip-off. Banksy is a bloody sod.” Diane Shakespeare, an official with the Keep Britain Tidy campaign, told me, “We are concerned that Banksy’s street art glorifies what is essentially vandalism,” while Jonathan Jones, of the Guardian, recently wrote on his blog, “I think there’s some wit in Banksy’s work, some cleverness—and a massive bucket of hot steaming hype.” But for every litter freak or culture purist driven to indignation by Banksy there’s a person who is entranced. While setting up the show in Los Angeles, Banksy ordered a pizza, ate it, and tossed the box in a Dumpster. Within weeks, the pizza box was sold on eBay, for a hundred and two dollars. The seller suggested that a few anchovies that had been left inside might yield traces of Banksy’s DNA.
