A rare self-portrait by Renaissance master Leonardo da Vinci has gone on display near the northern Italian city of Turin.

The canvas, which is insured for $67 million, has only been publicly shown twice before — in 1929 and 2006. The portrait is housed in the Royal Library in Turin.

The painting portrays the artist as an old man and is the star attraction of an exhibition entitled “Leonardo: The Genius and the Myth.” The exhibition runs through January 29, 2012, at the Reggia di Venaria, a 17th-century former royal residence near Turin.

The work of art is rare because Italian Renaissance masters infrequently painted or drew self-portraits.
