A rare piece of artwork from notorious street artist Banksy went up for auction last night — only to self-destruct moments after it was sold.

According to The Art Newspaper, copy of one of Banksy’s better-known works – the “Girl with a Balloon” painting – was auctioned at Sotheby’s in New York City, garnering a record-setting bid of $1.4 million. Once the bidding had come to a close on the iconic Banksy piece, the artwork started to sound an alarm and was subsequently destroyed by a shredder hidden within the frame. Staff proceeded to rush the artwork out of the room before it could be fully shredded.

The spray-painted canvas “Girl With Balloon” went under the hammer at Sotheby’s in London on Friday night, equaling a record price for the artist. Then, as an alarm sounded, it ran through a shredder embedded in the frame, emerging out the bottom in strips.

A post on Banksy’s official Instagram account showed the moment with the words “Going, going, gone…”

Alex Branczik, head of contemporary European art at the auction house, said: “It appears we just got Banksy-ed.”

Banksy, who has never disclosed his full identity, began his career spray-painting buildings in Bristol, England and has become one of the world’s best-known artists.
