The Lost Leonardo – Leonardo da Vinci and the Portrait of Isabella d'Este

In 2013 an oil painting attributed to Leonardo da Vinci appears in Lugano, the portrait of Isabella d'Este, Marchioness of Mantua. The owner of the painting, Emidia Cecchini, is about to sell it for 140 million euros when Italy accuses her of illegal export. The painting is confiscated, but Switzerland does not release it.
