David Kunzle, Distinguished Professor Emeritus, UCLA, has been supportive of the CSPG from its founding. He has written a number of books and articles, many of which deal with political posters, murals, and popular mass graphic expression. He has often used CSPG for illustration of his writings, and most recently in his book CHESU-CRISTO: the Fusion in Word and Image of Che Guevara and Jesus Christ (Walter de Gruyter Verlag, Berlin etc.)
