Why Would Someone Pay Millions For A Copy Of The Mona Lisa?

In Sotheby’s recent New York Old Master sale, a copy of the Mona Lisa soared past its estimate of $80,000-$100,000 to sell for $1.69m. It seems extraordinary that someone would pay so much for a copy (in fact, that’s probably an auction record for any copy). Then there is the fact that the painting had been offered privately before the auction for considerably less, but with no takers. Some have seen the transaction as suspicious. – The Art Newspaper
