I try to identify sets in a large bag of unsorted Lego (will probably have to ask some more of these in the coming days).
This piece is a real odd-ball: A black door with (mostly silver) stickers on both sides. I'm not sure if the door-frame goes with it, because they were separated in the bag, but it is the only door-frame in the whole bag.
The frame looks almost white, but it is actually grey. The shiny silver really messed up the white-balance of the camera.
