Imagine discovering that the painting you bought for a mere $19,000 just might be worth a cool $150 million -- all because a fingerprint was found in the paint. That's what may have happened to the owners of "Profile of the Bella Principessa." For years the painting has been in private collections. It was purchased at auction in 2007 for $19,000 by a Swiss art collector. But then things got very interesting...

Leonardo da Vinci not only used brushes when he painted, but he also utilized his fingers and hands, often leaving behind fingerprints in the process. When examining "Profile of the Bella Principessa," art experts found a fingerprint which, upon closer examination, matches fingerprints found in another da Vinci painting.

Fascinating! Later this month I'm interviewing Dr. William Wallace, one of the art world's foremost experts on Michelangelo and author of a new biography. You can bet I'll be asking him about the intersection between art and technology in our ever-changing world.
