A painting by mysterious British artist Banksy shred itself into pieces at the moment it sold for more than €1.2m at a London auction yesterday.
'Girl with Balloon', one of Banksy's best-known works, disappeared into a shredder hidden in its frame as the hammer fell at £1,042,000 pounds (€1.2 million), a sum that matched the artist's previous record sale, auction house Sotheby's said.
"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 onlookers 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.
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 Bristol, England, Banksy's work has become hugely valuable.
Girl With Balloon appeared on a wall in Great Eastern Street, London.
The gallery version featured spray paint and acrylic on canvas, mounted on a board. Sotheby's refused to reveal who had bought the piece before it was shredded.
