Da Vinci

I just watched a video on Yahoo! about the discovery of a new sketch in one of Leonardo Da Vinci's notebooks. What makes this discovery so important is that it is believed to be a self-portrait when he was young, which is very rare to see. The researches performed an "aging" simulation on the portrait and compared it to his later ones, and it virtually looked the same. The reason why it was never found was because it was very faint and he simply wrote over it in his typical "mirrored" handwriting. A journalist was going through the notebook when he made the discovery after spotting the off-colored area in the book.
