In the IWM North in Salford Quays is an impressive painting by Walter Bayes:
The image is distinctly (and understandably) reminiscent of the more familiar pictures of tube stations during the Second World War. It depicts civilians sheltering from the an air raid in the tunnels and on the platform at Elephant and Castle.
Twenty two years after the end of the Great War, in November 1940, Bill Brandt went into that same underground station in South London and photographed Londoners sheltering from the next generation of German bombers.
