Description: Interfunktionen, an art journal which published 12 issues between 1968 and 1975 in Cologne, was founded in 1968 as a form of protest by artists who had no affinity with the critical lines that were redrawn at Documenta that year. The review was of considerable importance as a vehicle for propagating pro-European ideas and as a union between artists in Europe and the United States, irrespective of the predominating movements of the time. It contained both theoretical and practical contributions, with the intervention of creators who defined and illustrated their artistic strategies. Directly linked to the most prominent figures in the Dsseldorf Kunstacademie, such as Joseph Beuys, Jorg Immendorf, and Sigmar Polke, it also boasted the involvement of the most spirited and reflexive artists of the times, from Vito Acconci and Marcel Broodthaers to Bruce Nauman and Dieter Roth. Interfunktionen, as its name indicates, was an inter-disciplinary publication, open to all artistic genres and with no restrictions as to media. This book is produced in collaboration with Fritz Heubach, the review’s first editor, and depicts the experience of those years by means of original documents–some of them hitherto unpublished–artworks, and artists’ writings.
