We’d never noticed this before, or even heard it mentioned anywhere.  However, when it was busy and we had to wait in line for The Flying Dutchman, we noticed that the plain walls weren’t so plain!  There are faces there.  We only managed to get a photo of one, but we noticed a couple in the first room you enter.

The other one was slightly different, but they were both subtle enough so that you wouldn’t notice them straight away.  Has anyone else noticed these?
