It turns out the famous shredding of Banksy's most famous artwork at a London auction earlier this month may not have gone quite as planned.
Banksy has posted a video on his website showing his million-dollar 'Girl with Balloon' piece was meant to have been destroyed all the way through.
At the auction it only went halfway.
At the end of the video, it notes that in rehearsals it worked every time.
The buyer has said she will keep her purchase as her own piece of art history.
