In 1961 Marcel Jean explained the full significance of this work’s disturbing zippered eyes: ‘The zip fastener [in French fermeture éclair – ‘lightning fastener’] is introduced as a plastic translation of another current expression des yeux qui lancent des éclairs – “eyes flashing like lightning”.’ In order to create the sculpture, Jean covered a plaster copy of Jean-Antoine Houdon’s eighteenth-century bust of Madame du Barry, the mistress of Louis XV, with fabric and black paint.
