Fascinating article on Art Superdealer Larry Gagosian that appears in the January 28, 2013 issue of New York Magazine: http://www.vulture.com/2013/01/art-superdealer-larry-gagosian.html
Gagosian has been, for the past two decades, the most powerful gallerist in the world, by a wide margin. In 2011, a survey of dealers in The Wall Street Journal estimated that his annual sales approached $1 billion. That May, roughly half the works for sale by the major auction houses in New York (evening sales only) were by artists on Gagosian’s roster. In addition to his three gallery spaces in New York, he owns two in London, two in Paris, and one each in Beverly Hills, Rome, Geneva, Athens, and Hong Kong. “In many ways, having a show with him is synonymous with having a show at MoMA or the Tate Modern,” says Eric Shiner, the director of the Andy Warhol Museum in Pittsburgh.
