That distant rumbling sound is the art market juggernaut approaching New York for two weeks of auctions of Impressionist, modern, post-war and contemporary art, Nov. 7-16, 2006. The sales have an absurd number of big-ticket properties, as they are called. Altogether, the ballpark figure for two weeks of auctions at Sotheby’s is about $500 million, while Christie’s is rather higher, around $700 million.
