This beautiful old 2 story dollhouse is offered by Acme doll shop. It is attributed to Christian Hacker. You can find it and more description on Ruby Lane Antiques. http://www.rubylane.com/
The ridges down the sides are called Quoins and often are an attribute of Christian Hackers.
Look at the old stove and beautiful wallpaper.
I love the beautiful muted colors and unlike many old dollhouses it does not seem tampered with. All comments welcome about this beautiful house. CM I want to add I have no affiliation with the company selling this dollhouse.
