But in a clip entitled Shred the love, the Director's Cut, the secretive artist said that the shredding had worked "every time" in rehearsals, alongside footage of an identical-looking artwork being shredded from top to bottom.
The auction of Girl With Balloon attracted a winning bid of £860,000 (approximately $1.4 million once the buyer's fee was factored in).
After the anonymous British artist self-destructed one of his most iconic artworks, "Girl with Balloon", some art experts had questioned how it was possible to pull the stunt off without Sotheby's (auction house) knowledge.More news: Ohio State QB Dwayne Haskins Tweets Message For Nick Bosa

Banksy has posted a video showing how he managed to shred his Girl With Balloon painting immediately after it was sold at auction. Partial shredding of the masterpiece is shown, as auctioneers rushed to take the work off the wall and out of the room.
"Some people think it didn't really shred".
Perhaps in the end the real story isn't that Banksy destroyed his painting, but ended up creating a new piece of art after all even when it didn't go completely as planned.
He said the reason the shredder wasn't detected by Sotheby's staff is they had been instructed the frame was a key part of the work.
