When I first looked at this photo, I thought the item in the background might be a calendar. In fact it’s a page of display ads for a sporting goods store that has been placed over some sort of opening,   like a window covered with a heavy screen.

That’s something of a pattern in these photos. Many pictures have a window in the background that has been covered up, either with tinfoil, or cardboard and blue masking tape.
