While some art fair-goers dutifully nursed their hangovers, others of us trudged up to Pier 94 early Thursday morning for round two of the Armory Show. One hundred and sixty exhibitors presented a daunting task, indeed, but the high caliber of the artwork more than compensated. Emmanuel Perrotin, Paris, displayed a small but impressive arsenal of works, among them Takashi Murakami's Louis Vuitton homage "Monogram Sphere." At the nearby Deitch Projects stall, wunderkind Ryan McGinniss' "Master of Reality" warranted a veritable queue. Another New York gallery, Matthew Marks, also impressed with works by high-profile artists such as Andreas Gursky and Katarina Fritsch. Hot off the Gursky trail, I subsequently made a beeline for London's fêted White Cube gallery, but none other than Mary-Kate Olsen was in my way. Survey says: New York is still the reigning queen of contemporary art.
