This image I'm not so sure about. I can see what you're talking about. But if you take the image, re-invert it back to its original. And then bright up the brightness so you can see some detail.
Look in the area that you've circled. I'm thinking it looks like the panels of a door, and perhaps a brass or bronzed door knob. The old style door knob with a handle that you push down, rather than a round one.
I'm assuming the bright area to he left is a mirror?
