Sorry about that! The room where they're sitting looks exactly like the salon at Villa Philbrook, an Italian-style joint built in the 20's by Waite Phillips, one of the Phillips Petroleum brothers. It's a museum now. Waite also gave Philmont Ranch to the Boy Scouts; he got bored easily.
The feet were just a random observation.
