A dozen scientists and one art historian have concluded that a recently-discovered painting appears to be a Leonardo da Vinci self-portrait.

The work was found in 2009 by a medieval historian studying the art collection of a family in Acerenza, a town in southern Italy.

After analyzing elements such as the pigments used, fingerprint impressions, and an inscription, as well as carbon dating the painting, the expert panel, which included David Bershad, an art history professor at St. Mary's University College in Canada, announced that the painting was likely an authentic Leonardo depciting the master himself.
