London, UK. 12 July, 2019. A poster at a bus shelter in Finsbury Park by street art collective Protest Stencil draws attention to the Science Museum having partnered with Raytheon, a US weapons manufacturer which sells arms used by Saudi Arabia for attacks on civilian areas in Yemen, for sponsorship of its new ‘Top Secret’ exhibition. Protest Stencil last week withdrew artwork from the exhibition in protest against Raytheon’s sponsorship.
