Pablo Picasso’s grandson, Olivier Widmaier Picasso, will raffle off Man in the Opera Hat (1914) to raise funds for the International Association to Save Tyre. The Lebanese city of Tyre is a UNESCO World Heritage site whose history goes back to ancient Phoenicia.

Picasso will sell 50,000 raffle tickets for $135 a piece and a winner will be drawn during an event at Sotheby’s in Paris on December 18. The market value of the small Cubist gouache is said to be around $1 million. The raffle money will go towards creating an arts center and educational institute in Tyre, which has been severely damaged by decades of military conflict.

Picasso will travel to New York in December with the work to promote the raffle. To date, 40,000 raffle tickets have been sold.
