Amy's wall, end of Flesh and Stone - actually was looking closely because I thought the picture above her bed might be a Van Gogh... Anyway, spotted something much more interesting. The photos on the wall to the left of Amy in this screenshot, I've circled a few - top left looks like it could be Tennant, though obviously easier to see without the circle. Next, down and right, looks like Rose. Below, possibly one of the clockwork men from the Girl in the Fireplace (tho tommyroxx thought it could be Amy, and somebody else suggested Liz Ten) and then the sketch looks a bit Madame de Pompadour-y. Just above the sketch, uncircled, the pic looks like a girl in a maid's outfit.
Anyway, thoughts? Am I seeing things? If not, how does this tie in?
