Richard Pettibone developed an eye for scale through a childhood interest in model trains. He brought this attention to a series of miniaturized reproductions of artworks by Marcel Duchamp, Andy Warhol and here, the Pop artist Roy Lichtenstein in his “Roy Lichtenstein, ‘Picasso’s Woman with Flowered Hat,’ 1963.” The original source for “Woman with Flowered Hat” was a 1941 portrait by Pablo Picasso. In 1963, Lichtenstein re-created Picasso’s painting in a scaled-up version that incorporated his signature Ben Day technique. By making a miniature after Lichtenstein’s own copy, Pettibone uses the reduction of scale to emphasize the objecthood of such monumental paintings, even replicating the stretcher bars across the picture’s back (visible in the mirror behind the work). Pettibone’s miniature coyly extends the questions of authenticity and authorship initiated by Lichtenstein while acknowledging the role of scaled-down replicas and reproductions in transmitting the history of art. See this and other works by artists who have employed the miniature in “Modernism in Miniature,” closing January 9th.
