As reported at the site of the auction house, after the last hammer strike, the work sold for £ 1.042 million ($ 1.4 million) began to be destroyed by a device for shredding paper hidden in a frame.
Confirmation has also appeared in the artist's Instagram.
Commenting on the incident, the head of the department of modern art at Sotheby's Alex Branchik noted that the destruction of the painting at the time of its sale is a kind of another masterpiece of Banksy.
