Brilliant!!
Banksy artwork shreds itself after £1m sale at Sotheby's - [bbc.co.uk]
yeah deff a stunt having worked in auction houses no where near as prestigious as sothebys everything in is double/triple checked esp on day of sale you can't miss a shredder built into a frame
Could believe the thin vent overlooked, to not want to take it apart to cause damage/also a stunt..How do they really know what Banksy who is anonymous truly did himself anyway..Not that it matters terribly. The statement seems to say this is ridiculous to spend all this money at an auction on my art when you could better spend it elsewhere.
