Between 1984 and 1985, Jean-Michel Basquiat (1960-1988) and Andy Warhol (1928-1987) created around 160 paintings together in tandem, à quatre mains, including some of the most remarkable works produced during their respective careers. Keith Haring (1958-1990), who witnessed their friendship and collaboration production, would go on to speak of a "conversation occurring through painting, instead of words," and of two minds merging to create a "third distinctive and unique mind." Accompanying an exhibition at Fondation Louis Vuitton, this book illustrates more than 100 paintings jointly signed by the two artists.
