An inlaid wooden chest the size of a shoe box holds Lynn Knight's button collection. A collection that has been passed down through three generations of women: a chunky sixties-era toggle from a favourite coat, three tiny pearl buttons from her mother's first dress after she was adopted as a baby, a jet button from a time of Victorian mourning. Each button tells a story. 'The Button Box' traces the story of women at home and in work from pre-First World War domesticity, through the first clerical girls in silk blouses, to the delights of beading and glamour in the thirties to short skirts and sexual liberation in the sixties.
