A painting by Pablo Picasso" Les Femmes d'Alger" could set a new record for the most expensive art work ever sold at auction. The masterwork, entitled "Les femmes d'Alger (Version "O")" goes under the hammer in May, according to auction house Christie's. Christie's estimates it will sell for $140 million. However, Picasso's most famous paintings are in high demand and such auctions usually sell for a much higher price than the estimate. Currently, the most expensive art work ever sold at auction is Francis Bacon's "Three Studies of Lucian Freud," which went for $142 million in 2013. That series of three portraits was expected to get just $85 million before it sold. Picasso's "Les femmes d'Alger," ("The women of Algiers") was last sold at auction for $31.9 million in 1997.
