Marta Minujín is an Argentine conceptual and performance artist. Minujín began her career in Paris. She then moved to New York, where she met Andy Warhol, whose influence can be seen in her works that satirize consumer culture. One of her best-known works from those years, Minuphone (1967), invited viewers to enter a telephone booth, dial a number, and watch as sounds and colors projected from the glass panels, while a television screen on the floor displayed the caller’s face. Minujin created a monument to freedom of expression following the return of democracy to Argentina in 1983. One of her best-known works is The Parthenon of Books (1983), in which a structure built of newly unbanned books in Buenos Aires. The books were later distributed to the public.
