“In the auction world, all it takes is three determined people with big egos and bank accounts to match. That’s why a 1917 Klimt landscape sold for $29.1 million last night at Sotheby’s sale of Impressionist and modern art. The price surprised even the auction house experts. The painting, which depicts a house and its flowering gardens in a rich tapestry of colors, wasn’t the only bright spot of the evening. The best works fetched high prices, but some of the rest went unsold without so much as a nibble.”
