Vanity

All is Vanity by Charles Allan Gilbert

I just bought a print of this after being haunted by it for about 20 years. I first saw it in elementary school as some sort of "trick of the eye" exercise. This was when art class existed in elementary school--or in school at all for that matter.

It's not the best done work of all time and I'm not sure if the original is in a museum or anything like that but I can't stop staring at it.
