More creepy faces

We went to the Cambridge Chophouse for a project end celebration dinner tonight. We were in the converted basement which had this funky / creepy wallpaper on one wall.

We were especially fascinated by the fact that all of the faces are the same woman and that the one wearing a necklace is wearing a necklace of lots of little faces - all still the same face.

I'm sure this is some famous art image that has been used but I missed the reference if it is. It slowly got creepier as more wine was consumed. I felt like I was being watched.
