Admired by Charles and Ray Eames, Buckminster Fuller and Saul Bass, Sister Corita Kent (1918–1986) was one of the most innovative and unusual pop artists of the 1960s, battling the political and religious establishments, revolutionizing graphic design and encouraging the creativity of thousands of people – all while living and practising as a Catholic nun in California. Mixing advertising slogans and poetry in her prints and commandeering nuns and students to help make ambitious installations, processions and banners, Sister Corita's work is now recognized as some of the most striking – and joyful – American art of the 60s. But, at the end of the decade and at the height of her fame and prodigious work rate, she left the convent where she had spent her adult life. Julie Ault's book is the first to examine Corita's life and career, containing more than 90 illustrations, many reproduced for the first time, capturing the artist's use of vibrant and day-glo colours.
