I follow Daddy Types' blog as he has a good eye for retro kids' toys and furniture, including dolls houses, and also vintage kids' books. He's just posted about a dolls house shown at the 2010 Toy Fair, the Emerson House by Brinca Dada, and a family of dolls house dolls they've also put out.
The Brinca Dada website says the dolls house will be available in (northern hemisphere) spring - and they will also have furniture for it! It's in 1:18 scale (also known as 3/4" scale). I wonder which of my blogging friends will buy one first?
