Poster; Billy Brown of London Town; I trust you'll pardon my correction, by David Langdon, 1941

This poster was commissioned by London Transport in 1941. Copies would have been posted in Underground carriages above the windows, which during wartime were fitted with anti-splinter netting to minimise blast damage. The cartoon character Billy Brown of London Town was created by David Langdon. Billy was an exemplary passenger used by London Transport to provide the public with wartime information and advice. In this poster he reminds a thoughtless passenger of the importance of anti-blast netting. The slogan 'I trust you'll pardon my correction that stuff is there for your protection' was written by Joan Chapman, a London bus conductor. It became a well-known motto among passengers, although the message was not always gratefully received. The standard graffito addition at the time was: 'Thank you for your information, but I can't see my b****y station'.
