Artwork doesn't have to be 'great' to be priceless, it can have a famous story behind
it, and be highly sought after by collectors. Although in the case of Leonardo DaVinci,
he truly was a genius. The Mona Lisa is special because of her smile. She's smiling,
but it's hard to pin down exactly where. Because if you cover her mouth, she still
appears to be smiling. If you are unable to appreciate Leonardo's art, you may not
have the ability to appreciate anything.
