Now available: old photos of the Family Dining Room, Master Bedroom, and Living Room in the 19th century. These were tricky to date, and I might not have them right yet.
UPDATE: I went back in and found a few pictures that offered zoom functionality. This allowed me to get more detailed captures of parts of the image, which was helpful in the case of the stereographs. Still working on the Red and Green, State Dining, Yellow Oval, and north and south face pictures.
