My aunt made them in the 1990's. She bought some of the miniatures that are in the houses, and a friend of hers built at least one of them. All three houses focus on living/dining rooms. All are made from wood. The first house has a dog in the center of the room, a fireplace, a red rug, a blue chair and a couch The second house features a dining table, two sides cabinets, a bay window, and a potted plant The third has a glass frame over it that has come loose, so I photographed it that was to show more detail. It features a a chair, side table, and two mini paintings on the walls.
I can get back to you with this information.
