War fears loom over this year’s Maastricht Art Fair. “Traditionally this small Dutch city has been an annual mecca for serious collectors from all over the world. But officials here report that attendance at this, the world’s largest art fair, will be down about 10 percent from last year. There are far fewer blockbusters than in recent years. Not only are great works of art getting harder to find, but often when dealers do have something extraordinary, they tend to hide it away during bad economic times, afraid that if it doesn’t sell, it will become overexposed and therefore less desirable. Dealers definitely seemed to be holding back this year.”
