Lewis Morley's photograph of Christine Keeler sitting naked the wrong way round on an Arne Jacobsen chair has become one of the defining images of the 1960s. A combination of pin-up and icon, suggestive both of sexual liberation and at the same time of the penalties of sexual exploitation, it occupies a morally ambiguous universe. It was taken in May 1963, when Christine Keeler came to Lewis Morley's studio over the Establishment Club in Greek Street to be photographed to promote a film on the Profumo Affair.
