Art Experts Believe Painting of Young Woman can be Attributed to Leonardo da Vinci

Art experts believe they have identified a new Leonardo da Vinci -- in part by examining a fingerprint on the canvas.

Peter Paul Biro, a Montreal-based forensic art expert, said Tuesday that a fingerprint on what was presumed to be a 19th-century German painting of a young woman has convinced art experts that it's actually a Leonardo.

The first previously unknown work by Leonardo Da Vinci to be discovered in a hundred years, a 13-by-10-inch chalk, ink and pencil drawing being called "La Bella Principessa," has been identified via fingerprint evidence. Using forensic technology, a Montreal-based forensic art expert has matched a fingerprint and palm print on the work to that of Leonardo Da Vinci, who apparently left fingerprints on many of his art works. The unsigned drawing had previously been attributed to a 19th Century German artist, until a collector purchased it on suspicion that it looked older than that and that it looked like Da Vinci's work. Experts now believe it is a portrait of the daughter of a 15th Century Milanese duke, and it was basically being used to pimp her out to prospective suitors -- not unlike profile pictures people use today to sell themselves on internet dating sites.
