On your right is Leonardo's Mona Lisa . On your left is a mirror image of the painting with a manga image stuck in her eye. Move back from your monitor? Does it disappear?
If you move further back (like several feet from your screen), the manga will completely disappear into her face. Check out the smaller image for reference.
The manga is from 1990s macho manga Baki the Grappler and depicts character Retsu Kaioh—or, rather, Mona Lisa's eye.
