This artwork was stencilled onto this wall on Frogmore Street in Bristol by Banksy in 2006. My photo is from 2013, after the artwork was vandalised with a paintball gun which had fired blue paint at it, but before it was attacked with black paint. It’s five metres up from the floor, which required Banksy to erect scaffolding and the council discovered the artwork when they removed that structure.
Although Banksy had been painting on walls in Bristol for some time before this, the artwork gave the city council a challenge. They were against graffiti on buildings, but the works produced by Bansky proved popular with locals and they were of a higher quality than much of the other graffiti that was scrawled onto walls. So, in this case, the council went along with it and it has remained in place since.
