Exhibitions
The Landmark exhibitions from August 1968 to August 1969 were staged in London, New York City and in Zagreb. During both exhibitions in Zagreb, international scientific symposiums were held. Another exhibition and conference was held in Berlin. The Cybernetic Serendipity exhibition in London over the years received the most attention in secondary literature. Today, it is dependent on the nationality and education and research level of the observer as to which of the three they consider the most important. There were already critical voices about the 1968 exhibition in London. Gustav Metzger was at the Tendencies 4 symposium in Zagreb and wrote 1969 a critic in a journal by Studio International:  At a time when there is a widespread concern about computers, the advertising and presentation of the I.C.A.'s ′Cybernetic Serendipity′ exhibition as a ′technological fun-fair′ is a perfectly adequate demonstration of the reactionary potential of art and technology.
The Human Figure by Fetter was seen in all exhibitions as Boeing Man. In the catalog for Cybernetic Serendipity only The Boeing Computer Graphics organization is mentioned as the author.
