GOOD for Italian woman Natalia Strozzi and her sister Irina, who have been officially certified as the Mona Lisa's closest living descendants.

Theirs must be the most amazing treasure in the genealogy world.

But has anyone ever noticed the strange, almost eerie facial likeness between the Mona Lisaand Prince Charles's portrait on the stamp issued for his 1969 Investiture?

The two could quite easily be blood-related as well. I don't suppose the Mona Lisa had a stutter, did she?
