“Frank Lloyd Wright’s wood-block model for the Imperial Hotel in Tokyo. Paper neckties with flowery designs by Picasso. Mies van der Rohe’s ‘projects-general correspondence 1920’s 1930’s.’ MoMA’s first guestbook from 1929. A rich trove of background for all the legendary works in the Museum of Modern Art will become more accessible to the public with the opening today of MoMA’s new education and research building in Midtown Manhattan.”
