1995. The Beverly Hills gallery mounted exhibitions by Edward Ruscha, Nan Goldin, Frank Gehry, Jeff Koons and Richard Prince. It also showed modern artists such as Pablo Picasso, Roy Lichtenstein and Abstract Expressionism group exhibitions. To finance Koons's giant "Celebration" sculptures, a consortium of dealers, including Gagosian, spent years helping the artist line up buyers willing to prepay for them. The buyers paid $2 million to $8 million apiece to own one of the artist' car-sized sculptures of balloon dogs and candy-colored hearts. In 1999, Gagosian Gallery moved from SoHo to West 24th Street, in New York's industrial Chelsea. Richard Gluckman designed the gallery in which Richard Serra presented the monumental sculpture, "Switch," in November 1999. The new space was fully completed in September. The large viewing space at West 24th Street allowed Gagosian artists, such as Richard Serra and Damien Hirst, to exhibit large scale works with great flexibility. 2000s In spring of 2000, Gagosian became an international gallery with the opening in London of a Caruso St John-designed space on Heddon Street, near Piccadilly, then the largest commercial art gallery in London. The UK gallery inaugurated its exhibitions program with a performance by the Italian artist Vanessa Beecroft, followed by an exhibition of works by Chris Burden. In September 2000, in New York, Gagosian held the Hirst show, Damien Hirst: Models, Methods, Approaches, Assumptions, Results and Findings. A second London Gallery, also designed by Caruso St John, on Britannia Street, opened in May 2004 with a paintings and sculpture show by Cy Twombly. Comparable to the Chelsea exhibition space in size, this addition was then the largest commercial art gallery in London. It accommodated large sculpture, video pieces and installations such as Martin Kippenberger's show, The Magical Misery Tour, Brazil. The Heddon Street location closed in July 2005, and a new storefront space on Davies Street opened simultaneously with an exhibition of Pablo Picasso prints. To complement the West 24th Street gallery, a Richard Gluckman designed space on West 21st Street opened in October 2006. A joint exhibition with the 24th Street gallery, Cast a Cold Eye: The Late Works of Andy Warhol, launched Gagosian Gallery's second location in Chelsea and third location in New York. In 2009, the 21st Street gallery held an exhibition of Pablo Picasso's late works entitled Mosqueteros, curated by Picasso historian John Richardson. The Madison Avenue location introduced a fifth-floor gallery space, set
