The saloon, Sezincote, Gloucestershire from The Regency Country House by John Martin Robinson.
Described in the caption: "The bow window, the form of the curtains, the trompe l'oeil gilt trellised cove, and the large looking-glasses all survive from the original 1820s decoration, and make this a pure Regency interior."
