Banksy's 'Spy Booth' street-art, which has been painted to the side of a private residence in Cheltenham in the west of the UK, has been granted Grade II Listed status by the local authorities. The protective rights, which are generally reserved for historically significant structures and facades, mean that it is illegal to alter or remove the work. Great news for Banksy who knows this piece will be preserved in time.

The mural popped up in April of 2014 amidst the media controversy of government security agencies over extending their abilities to surveil and spy on citizens. Banksy's clever statement sees an old fashioned phone box surrounded by three spies using various equipment to eavesdrop on the phone booth. 

Banksy took to his website to respond to the news of his listed status with a brief and tongue-in-cheek interview: 

What do you think about your graffiti being granted Grade II listed status?

It's surprising because when I did art at school I got an "ungraded."

What's the worst thing about street art?

Having to make your mistakes in public.

What do you think about people selling the art you put on the street?

As a kid I always dreamt of growing up to be a character in Robin Hood. I just never realised I'd end up playing one of the gold coins.
