Thank you for posting the pictures. Again, the image of the face can sort of be seen in photos of “The Last Supper”. However, the image is quite distinct in person (two dark eye sockets and a mouth gaping open—not a joyful face)

I was just wondering if anyone who had actually been to see the painting noticed something similar.

Can someone tell which region of the painting one needs to be looking at, to find the face?
