Debate - Is the astronomical price paid for some paintings by private collectors justified?    In May 2010, 'Nude, Green Leaves and Bust' a painting by Picasso was sold at $ 106 million to an unknown bidder (most probably to a private collector) by an auction house in New York. Is the astronomical price paid for some paintings by private collectors justified? Is it just an investment which will fetch good returns when sold at a later day, or do the collectors truly love the work so much that they pay such large amounts to bring them to their home so that they can enjoy the painting each day?
