Sister Corita Kent was one of the most innovative and unusual pop artists of the 1960s, battling the political and religious establishments, revolutionising graphic design and encouraging the creativity of thousands of people - all while living and practicing as a Catholic nun in California. She was respected and admired by Charles and Ray Eames, Buckminster Fuller and Saul Bass but more importantly she brought unconventional systems of graphic communication to the masses which still look ahead of their time.
