Quote KatStevens: I read your initial post & it made me curious about the four chairs, too. When did the picture first appear in the show? When I noticed the picture was included in the scene after Tom & Margo's move, it seemed all the more that it has some meaning beyond being a piece of art. I have no idea what, but would like to know! My mind tends to go overboard with things, so maybe it's merely a piece of art.
It has been there for years. Long ago there used to be a staircase back there and a hanging with smaller squares and smaller chairs was there. Over time they changed it to the larger squares. It is one of those things that I have always wondered about. I don't even know where to go to ask that kind of trivia question. Probably too late now!
