This is one of the most famous works of art, and you probably recognize the painting AND the artist's name. DaVinci was a painter, a scientist, and an inventor. His artwork is well know by art historians, but is also part of popular culture.
This one, called Mona Lisa, from 1503 - 1506, is considered slightly mysterious. Her captivating smile makes us wonder what she is thinking about. There is also a lot of questions about who the model was, and if it could have actually been DaVinci himself.
The painting is actually quite small, (2'6" X 1'9") and people line up to see it in person.
