The first reproduction of Fountain was authorized by Duchamp in 1950 for an exhibition in New York; two more individual pieces followed in 1953 and 1963, and then an artist's multiple was manufactured in an edition of eight in 1964.[15] These editions ended up in a number of important public collections; Indiana University Art Museum, San Francisco Museum of Modern Art, the National Gallery of Canada, Centre Georges Pompidou and Tate Modern. The edition of eight was manufactured from glazed earthenware painted to resemble the original porcelain, with a signature reproduced in black paint.[16]
