Description  In October 2007, a striking portrait of a young
woman in Renaissance dress made world news headlines. Originally
sold nine years before for around $20,000, the portrait is now
thought to be an undiscovered masterwork by Leonardo da Vinci
worth more than $100 million. How did cutting-edge imaging
analysis help tie the portrait to Leonardo? NOVA meets a new
breed of experts who are approaching "cold case" art mysteries
as if they were crime scenes, determined to discover "who
committed the art." And it follows art sleuths as they deploy
new techniques to combat the multibillion-dollar criminal market
in stolen and fraudulent art.    PBS Airdate: January 25, 2012
