Corita Kent (1918 - 1986), a Sister of the Immaculate Heart of Mary, was one of a number of remarkable nuns teaching at Immaculate Heart College Lost Angeles in the sixties. She directed the art department there until she left the Order and moved to Boston in 1968. Beginning in the sixties, she increasingly gained renown for her use of pop art with both spiritual and modern themes, utilizing bright colors and contemporary quotes. Her commisions ranged from a banner for the Vatican Pavilion at the 1964 New York World's Fair to her 22-cent Love Stamp, commisioned by the US Postal Service.
