'We Just Got Banksy-ed:' Balloon Girl Painting Self-destructs at Sale and May Now Be Worth More

A painting by mysterious British artist Banksy shred itself into pieces at the moment it sold for more than 1 million pounds at a London auction on Friday.

Onlookers gasped and laughed after the bottom half of "Girl with Balloon", one of Banksy's best-known works, was sucked into a shredder hidden in its frame as the hammer fell, auction house Sotheby's said.

The 12-year-old painting had just been sold for 1,042,000 pounds ($1.37 million) - matching Banksy's all-time record.

According to ABC News, the stunt may actually increase the painting's value. "That makes it part of world art history," said to Joey Syer, the co-founder of MyArtBroker.com, "which will increase its appeal."

"It appears we just got Banksy-ed," Alex Branczik, senior director and head of contemporary art, said in a statement on Sotheby's website.

Banksy himself posted an Instagram picture of shocked attendees watching the painting disintegrate, with the caption: "Going, going, gone..."

Sotheby's said this was "certainly" the first time a work of art started to shred itself after coming under the hammer.

POP ART WILL EAT ITSELF

Video footage showed two men taking the painting away shortly after the sale, bits of the image hanging down from the bottom of the frame in strips.

The auction house was not immediately available for comment on the whereabouts of the painting's remains, or how its value might have changed in light of its self-destruction.

Banksy, whose real identity is unknown, is known for sharply ironic outdoor graffiti with political themes, including at Israel's barrier at the West Bank and Disneyland where he painted a life-size figure of a Guantanamo Bay detainee.

Once a small-time graffiti artist from the English city of Bristol, Banksy's work has become hugely valuable.
