I did some research and the closest house I could find was in an advertisement for Christmas 1946. ( see below- top right)
The advertisement states "Two story, 6 room Southern Colonial type dollhouse with stairway. Finished with black, green and red stenciled design. Blinds and roof are green, porch floor is red with white columns and roof. Painted floor with flocked rugs and stenciled linoleum. Made of Gypsum Hardboard. 29-1/4" long, 21-1/4" high and 16-1/4" deep. $4.69"
I found a currency converter online and $4.69 is roughly $100 in today's dollars.
The existing windows were in really rough shape. Its hard to tell from the photos, but they are cracked, starting to curl and the paint is cracking off them. They also have years of layers of glue and cellophane tape.
The photo shows the new replacements from the vinyl sign company
I began by peeling off the cardboard backing ( shown in blue)
I then placed the sticker on the sheet of mylar that I had cut to the correct size.
Once the sticker was in place, I burnished it down with a plastic scraper.
Once the sticker was firmly adhered to the mylar, I peeled of the protective backing.
Voila! a shiny new window.
This detail shows the "linoleum" floors and the blue flocked rugs upstairs and the green flocked rugs down stairs.
The view shows the new windows in place.
