It's been quite a while since we've done a "Guess the Decade" post, which means it's about time we did another! Today's room is a beautiful one, and hopefully one that trips up all you design-savvy people out there.
Check back tomorrow - we'll be posting the answer and the photo info then. Speculation and discussion is always welcome in the comments, but for those of you who may know the photo source info... please don't tell! Thanks!
Good luck to all of you!
