In the introduction, Gaglione mentions that Ben was the first to introduce rubberstampings into modern art in the late 50's and early 60's but that Kocman should be considered the "neo-father" of contemporary stamp art as demonstrated by his 1972 book "Stamp Activity." With this publication (30 copies), the concept of international stamp art was officially born into the eternal network. The rubberstamp collaged onto the cover carries the word, "touch." -- Source of annotation: Marvin or Ruth Sackner.
