“NO! NO! NO! to the conventional, to all the evil and despair that reign here, NO to conformism and materialism!” This sentence is published in the flyer of Boris Lurie (1924–2008) exhibition in The Gallery: Gertrude Stein in New York in 1963 and it depicts the exhibition dedicated to the NO!art movement that started in the late 1950s and early 60s as opposition to the trend of the commercialization of art.
