On 7 April, Banksy entered Natural History Museum disguised as an employee. He carried a taxidermied rat in a glass-fronted box. The rat wears sunglasses and a complete graffiti kit. Apparently, the rat has sprayed “Our time will come” on the wall behind him. The installation comes with a printed explanation titled “Pest Control”. A few years later, Banky will set up his own certification office, the “Pest Control Office”.
