Did you know that "The Mona Lisa" used to actually have her hair up in a bun and she had a more expressive smile? but Leonardo Da Vinci painted her hair down and as they cleaned it a bunch of times, her smile got more small. Also, cleaning it effected her eyebrows and eyelashes. She used to have those too. Leonardo Da Vinci kept the painting after her was officially "done" and was working on it for the rest of his life. He was born in 1452 and Died in 1519. He started the painting in around 1502 or 1503. On the "The Mona Lisa"s face, theres at least 30 layers of paint.
