This our Einstein Hollow Face Mask, but it has been hand painted so as to give an amazing life-like impression of Albert Einstein. A true work of art. Also, the optical illusion works incredibly well.

When you view the mask from the 'hollow' side, the face still seems to be sticking out towards you - the human brain just cannot compute a hollow face! As the camera moves left or right, the face seems to swivel, and follow you. And if the camera moves up and down, again, the face tilts, to follow you. Amazing. And even more realistic in real life!

This would grace the wall of any museum wanting to show amazing optical illusions!

Multiple layers of paint are needed in order to get the final effect, and it takes the painter a week's work to create one of these.
