Keep mum - she's not so dumb

DescriptionA careless talk poster, illustrated with the figure of a blonde-haired woman reclining, and officers from each branch of the Armed Forces about her, with the slogan ˜Keep mum she's not so dumb!' The slogan was an adaptation of the 1940 campaign, ˜Be Like Dad, Keep Mum', which had so enraged the Labour MP Dr Edith Summerskill.
