In the 1960s the Gallery of Contemporary Art, as it then was, in Zagreb organised five international New Tendencies exhibitions that in their themes were a continuation of the work of EXAT 51 and also brought out the importance of experimental visual research and industrial aesthetics. Ivan Picelj (1924 – 2011) was an active participant at these shows and a designer of posters for the event: the poster for New Tendencies 4 (1969) is a response to the overriding theme of the fourth exhibition (information theory, computer aesthetics).
