A new level of trolling by Banksy

The video shows the famously anonymous artist constructing the shredding mechanism inside an ornate frame and pushing a button in a black box to activate the destruction at Sotheby’s in London earlier this month. The act shocked the crowd, but the winning bidder, a European collector, went ahead and bought it anyway for $1.4 million, according to the auction house.

Sotheby’s did not name the buyer.
