“A week later we came back to the same tunnel with two buckets of paint and a letter. The letter was a forged invoice from a mickey mouse Arts organization wishing us luck with the “Tunnel Vision mural project”. We hung up some decorator’s signs nicked off a building site and painted the walls white wearing overalls. We got the artwork up in twenty five minutes and held an opening party later that week with beers and some hip hop pumping out the back of a transit van”.
The 'illicit outdoor gallery experience' consisted of over a dozen of Banksy's well-known stencil works including his 'Laugh now' chimpanzees, Lenin, Weston-Super-Mare and his Flower Thrower, executed directly onto the tunnel walls which he had pre-painted in white emulsion beforehand.
The rest, as they say, was history.
Very rare.
