NEW YORK.- It is almost time for the Museum of Modern Art to close its beloved Manhattan home on May 21, 2002, and open its branch in Long Island City, otherwise known as MoMA QNS, on June 29, 2002. Showpiece of the new facility, a blue-painted former Swingline stapler factory overhauled by Michael Maltzan Architecture and Cooper, Robertson & Partners, is the first complete installation of the museum's automotive collection, "Autobodies: Speed, Sport, Transport." Also slated for the big blue box are masterworks from the MoMA collection, "Tempo" (a show of works about time) and photos by Rudy Burckhardt from the 1940s called "A Walk through Astoria and Other Places in Queens."
