20TH-FLOOR VIEWS FOR JUDD AT CHRISTIE’S New York’s coolest new exhibition space is the 20th floor of the Simon & Schuster Building at 1230 Avenue of the Americas in Rockefeller Center, where Christie’s New York has put on view 36 Donald Judd works that go on the block on May 9-10, 2006. Installed in a raw, cement-floored office space flooded with natural light (and with striking vistas of midtown Manhattan), the works range from rare early pieces from 1962-63, fabricated in 1988 for Judd’s Whitney Museum retrospective, to a large Plexi and plywood stack piece made a year before the artist’s death in 1994. The exhibition dates are Apr. 3-May 9, 2006; visitors must show i.d. and get a special pass to enter the building.
