This image shows the bath-dressing room in Katherine Mackay's (Katherine Alexandra Duer (US1797spouse1)) bedroom. The website that posted this image (see below) describes it this way:
"A bisquit clock is introduced."
The clock can be seen at the center of the fireplace mantle.
Note: the good view of the sunken tub that can be seen on the left side of the photograph.
See Harbor Hill, Clarence Hungerford Mackay's Mansion.
