This new mural in Cheltenham, England, has all the markings of a new Banksy piece – narrative, graffiti style, and man-in-a-van execution. We’re just waiting for his website to confirm it.

Found by a Cheltenham mum, who “saw men with a maintenance van and a tarpaulin” setting up at dawn, Banksy’s choice of Cheltenham isn’t just at random. The crack at the NSA et al. given recent privacy issues is fittingly topical to the city, being the home of the Government Communications Headquarters, or GCHQ – the UK spy agency.

With the 1950s era spies and the variety of technology on show, Banksy might be suggesting they’ve always been watching us, it’s just getting more sophisticated.

We’ve found the decrepit phone booth on Hewlett Road, in Cheltenham, on Google Earth Streetview too, if you want to see the before/after.
