Is the mona lisa really van gogh?

No, the 'Mona Lisa' is a painting done by Leonardo da vinci during the Italian Renaissance, painted about 1503-1505. Vincent van Gogh was an artist active in France during the French Impressionist period, circa late 1800's. There has been speculation that the 'Mona Lisa' is a self-portrait of sorts of Leonardo himself, but no evidence exists to prove this theory.
