This article observes how the new understanding of art which was introduced at the end of the 1960s by pop art influenced groups was pursued and radicalised in the second half of the 1970s, in a period generally referred to as the weakening of the avant-garde. It focuses on the texts by Leonhard Lapin, promoting art as a means of creating a new living environment. Taking Lapin's text as a framework, the author analyses the intervention in the official exhibition of monumental art in 1976.
