Was Banksy at the evening sale at Sotheby’s on Friday night? That was the question on everyone’s lips when one of the Bristolian street artist’s paintings mysteriously self-destructed as the contemporary auction drew to a close.

Girl with a Balloon (2006) was the final lot of the night, and just as the canvas hammered at £953,829—exactly the same figure as the artist’s previous auction record, achieved in 2008—an alarm was triggered inside the work of art. Onlookers turned just in time to see the canvas slip through its faux-gilt frame and be shredded into pieces.
