“If money is any indication, the London sales have momentum. Christie’s reported a nearly 20% rise between the February sales and June sales. The total for the Impressionist, Modern, and Postwar Contemporary sales rose to $470 million from $392 million. Sotheby’s sold $408 million worth of art, their highest London total ever. Overall, the London auctions showed that the steady trends of the last two years are still in train.”
