Florida, where an 18,000-square-foot warehouse studio on Cocoanut Avenue enabled him to work on a much grander scale than he previously had. Many of the subsequent works Chamberlain made in Florida revert to more volumetric, compact configurations, often aligned on a vertical axis. As seen in the so-called Giraffe series (circa 1982–83), for example, linear patterns cavort over multicolored surfaces—the results of sandblasting the metal, removing the paint, and exposing the raw surface beneath. In 1984, Chamberlain created the monumental American Tableau created for display on the Seagram Building's plaza. Assembling intricately cut, painted metal parts, Chamberlain made his first mask, A Good Head and a Half (1991), for a benefit auction for Victim Services in 1991, providing aid to victims of sexual assault. He continued to produce masks throughout the 1990s in his studio on Shelter Island, titling many of them with opus numbers. Chamberlain also made abstract colour paintings from 1963, and from 1967 he made several films, such as "Wide Point" (1968), and "The Secret Life of Hernando Cortez" (1968), filmed in Mexico with Warhol regulars Taylor Mead and Ultra Violet. He also made the film "Black Cherry No-Cal" (1971), a short black and white experimental film about a man and a woman that meet in Central Park on a bench. In the last decade of his life, the artist expanded his work to large-format photographs. Exhibitions Chamberlain's first major solo show was held at the Martha Jackson Gallery, New York, in 1960. His singular method of putting discarded automobile-body parts together led to his inclusion in the paradigmatic exhibition "The Art of Assemblage", at the Museum of Modern Art in 1961, where his work was shown alongside modern masters such as Marcel Duchamp and Pablo Picasso. His works have since been exhibited around the world and have been included in the São Paulo Art Biennial (1961, 1994), the Whitney Biennial (1973, 1987) and Documenta, Kassel, Germany (1982) and he has had over 100 solo shows, including Dia Art Foundation (1983); Staatliche Kunsthalle Baden-Baden and Staatliche Kunstsammlungen Dresden (1991); Stedelijk Museum, Amsterdam (1996); and Menil Collection, Houston (2009). Chamberlain represented the United States at the Venice Biennale in 1964. He had his first retrospective in 1971, at the Solomon R. Guggenheim Museum, New York. A second retrospective was organized in 1986 by the Museum of Contemporary Art, Los Angeles. From February 24 to May 13, 2012, shortly
