The legendary image/text/print/performance artists' jounal founded in 1968 by Friedrich Wolfram "Fritz" Heubach on the basis of critical discontent with the market-friendly conservatism of Documenta 4. 12 issues in all, multiple formats. Heubach edited the first ten issues and was succeeded by Benjamin H. D. Buchloh, who edited the last two. 
        The journal may have continued were it not for the critical discontent aimed at a presumably critical, Nazi-inspired spread by Anselm Kiefer, about which Marcel Broodthaers infamously asked, "Who is this fascist who thinks he's an anti-fascist?"
