The Isleworth Mona Lisa is believed by some to be an earlier version of the famous work by Leonardo hanging in the Louvre. It bears a striking resemblance to the subject of the Mona Lisa, and appears to be a portrait of the same lady at a younger age.
It's authenticity is disputed, but recent carbon dating of the canvas puts it in the right period. The face and hands look very much like the work of Leonardo, but the neck and background are somewhat cruder, suggesting that another artist, or artists, may have finished a piece left unfinished by the master.
Roughly a century ago, An English art collector, discovered the portrait in a nobleman's house in Somerset, England. He bought the painting and kept it at his studio in Isleworth, London; hence the name. After languishing in a bank vault for half a century, the painting was finally revealed to the public a year ago.
