I have two faces for you today:
The one on the left is clearly Andre the Giant (which is funny, as the email about it came the day after watching "The Princess Bride". Inconceivable!), and on the right is Mother Teresa, who apparently had work done when this portrait was made. Unless it's Alfred E. Newman. Hard to say.
Both appear to me to be, as usual, random patterns that look like faces and, also as usual, once you see the face you can't not see it. Our brains are funny.
Tip o' the oil stain to Sam Lehman and Elwood Herring, respectively, for sending those to me!
