This room is called the Pavilion, where Ms. Post entertained guests after dinner, often with movies shown on a large screen that is rolled up by the ceiling. The seats have pop-up trays for snacks and drinks. The large painting is titled “A Boyar Wedding Feast,” a Russian revivalist work painted in 1883, 200 years after such a celebration would have taken place.
