The trouble with Banksy's artwork is that a lot of it is sprayed on walls. So if you want to exhibit his original pieces you have to take the wall down.
That's exactly what was done for the Original Street Works exhibition at the Keszler Gallery in New York. Walls were taken down in Los Angeles, Palestine, Brighton and New Orleans, and artworks dating back to as far as 2002 removed.
The video shows you the process of removing the Stop and Search and Wet Dog works from Palestine.
Banksy must have wondered why he bothered going all the way out there in the first place.
