Which London museum displayed a Banksy artwork secretly installed by the artist in 2005?

The British Museum displayed a Banksy artwork that the artist secretly installed in 2005.

Banksy placed a fake cave-painting panel in the museum’s Roman Britain gallery without permission. The image showed a prehistoric-looking hunter pushing a shopping trolley while a wounded animal appeared nearby. A label beside it described the piece in the style of a museum caption and gave it a satirical title.

The intervention commented on consumer culture, museums, and the way institutions decide which objects deserve historical importance. Museum staff did not immediately notice the addition. The British Museum later acquired the work, turning an unauthorised prank into part of its own collection. This is different from Banksy’s later public murals, which were generally made on outdoor walls.
