Jindrich Chalupecky contributed an introductory essay entitled "The Heretical Surrealism of Ladislav Novak." Novak describes his first meeting with Jiri Kolar in 1961 as one of the greatest experiences of his life. Kolar gave him "the kind of stimulus needed and the knowledge that in art one must be ruthless and thorough, that even the most brilliant idea isn't enough in itself, that one must develop it in series, push it, advertise it, etc." -- Source of annotation: Marvin or Ruth Sackner.
