From The Guardian:
“The graffiti artist Banksy has managed to smuggle in his latest work, a dead rat in a glass-fronted box, into the Natural History Museum where it was exhibited on a wall for several hours.
Staff did not notice that the rat was out of place amid the museum’s usual fare of dinosaur bones and artefact from the animal kingdom.
The rat was stuffed and clad in wraparound sunglasses, scaled down to fit the top of its head, a rucksack on its back, and with a microphone in one paw.
A miniature spraycan sits at the departed rodent’s feet, while above it is sprayed in graffiti-style lettering our time will come.”
