One of the last photographs of Tirzah. Her autobiography, Long Live Great Bardfield, which we publish in a month, is witty, brave, perceptive, interesting and totally without self-pity: Tirzah had a touch of greatness that is only now beginning to be recognised (there will be an exhibition at the Towner next year where – at last – she will be seen as a major figure in the 1930s art world).
