Artists Paul Butler and Linda Jane James visited the gallery and talked about their work on various murals including the Cable Street Mural in London. This is the video of the conversation mostly with Paul.
Another video interview with more detail about the mural at Cable Street is here:
Images of the mural at Cable Street can be found via Google search. The mural represents the Battle of Cable Street which took place on Sunday 4 October 1936 in Cable Street in the East End of London. It was a clash between the Metropolitan Police, overseeing a march by the British Union of Fascists, led by Oswald Mosley, and anti-fascists, including local Jewish, socialist, anarchist, Irish and communist groups. The mural has been damaged by malicious attack various times and has been restored again, which is mentioned in the second video above. More information about this mural can be found at http://cablestreetmural.tumblr.com/.
Another mural that Paul and Linda mentioned they have been involved in restoring is the Hackney Peace Carnival Mural.
Paul talked about a paint system, keim paint, a pure pigment paint system used for the murals, which is available commercially in the UK from http://www.keimpaints.co.uk/.
