If you want to make a statement, here's the formula: take an already bare wall, supersize a portrait of the wealthy from way way way back when, and plaster it on as if it were wallpaper, and voila! Your room is sure to be quite the conversation starter. And I love how perfectly nonchalant these fellas are, as if they just casually sauntered in, and oh! Why, you just caught me writing a letter! I didn't see you there! Or, oh! I just happened to walk through the door covered in multiple capes of fur (he's a boss) and there you are painting me.
In all honesty though, these rooms are probably the most dramatic I've seen and certainly the most unique. I was wowed.
