New York City's spring art auctions get underway Tuesday with exceptional pieces by Pablo Picasso, Alberto Giacometti, Vincent Van Gogh and others whose work continues to fuel a robust market for impressionist, modern and contemporary art. Picasso's "Women of Algiers (Version O)," estimated to bring over $140 million, is poised to become the most expensive artwork sold at auction, while Giacometti's "Pointing Man" could set an auction record for a sculpture if bidding soars to an expected $130 million.
