This piece appeared in 2003 in Shoreditch, east London, in the courtyard of the Cargo Nightclub on Rivington Street. It is one of Banksy’s cleverest jobs of turning bureaucratic language into his own weapon. The composition combines a fake notice imitating an official sign with a uniformed security guard standing stiffly next to a fluffy, tiny poodle. The sign reads: “BY ORDER NATIONAL HIGHWAYS AGENCY THIS WALL IS A DESIGNATED GRAFFITI AREA PLEASE TAKE YOUR LITTER HOME”.

The joke lies in the way the piece copies the language of official authority and, by doing so, reverses its meaning completely. A sign of the kind that normally bans graffiti here does the opposite, permitting it, complete with a ridiculously polite warning about litter. The security guard beside it, together with that tiny poodle, which is about as far from threatening as an animal can get, drives home just how empty and ineffective an official show of force can become. Banksy also tried putting similar fake permission signs at other points around London, to encourage other graffiti artists to use those walls.

The piece also touches on a basic contradiction inside street art itself. Graffiti is defined as an unauthorised act. Does it still count as graffiti once it has official permission? This mural in the Cargo courtyard has remained in place to this day, and over time it was covered with a plexiglass panel for protection, which produced an ironic result of its own: a piece that mocks institutional control ended up becoming an institutionally protected object itself.

Graffiti Area is perhaps the purest example of Banksy’s strategy of imitating bureaucratic, official language in order to collapse it from the inside. There is no violence and no explicit political message here, only a quiet but effective parody that exposes the absurdity of institutional language on its own terms.
