From a M.C.Escher letter:
Baarn, 20 April 1969:
"The Hippies of San Francisco continue to print my work illegaly. I received some of the grisly results through a friendly costumer over there.Among other things, such as virulently colored posters, I was sent a forty-eight-page programme or catalogue of the so-called "Midpeninsula Free University", Menlo Park, California. It included three reproductions of my prints alternating with photographs of seductive naked girls."
