Sister Corita. Philadelphia: Pilgrim Press, 1968 

“From the 1960s on, Corita’s work diverges more and more from the rules of legibility central to Modernist design. Language is excerpted, disassembled, re-assembled, recontextualised. Typography is distorted, reversed and turned upside down. Letterforms float and interlock. Pictorial space becomes a forum for a carefully orchestrated typographic dialogue. She quotes, combines, extracts, highlights and layers elements from a wide array of cultural sources, including song lyrics, advertising slogans, scripture, newspapers and magazines, street and grocery store signage, poetry, theological debate and philosophy.”

“The joyful style which Sister Corita discovered is juxtaposition. She uses phrases like ‘Come alive’ and ‘Fly the friendly skies’ and juxtaposes them in such a way as to take them out of their intended context. She puts them in the context of whimsy and affirmation and celebration and even makes of them a serious statement of hope just by using them for her own purposes. She re-creates them. In a sense, she snitches them. And the very fact that she snitches them for herself, makes it a humanizing statement.”
