If you were an art dealer at Armory Week with expensive paintings to sell, you probably went home disappointed, like David Zwirner, whose Bernie Madoff portrait didn't find a buyer. "I went there with low expectations, said Zwirner gloomily "and they were not met." According to New York's Alexandra Peers, the works that sold at the Armory Show and its satellite fairs like Volta and Pulse were cheap (meaning under $25,000) and tended to look "homemade, handmade, self-conscious."
