I just wanted to bring a new dollshouse exhibition into your focus. It'll open at 30th of June at Newby Hall. Caroline Hamilton is one of the founders of the Kensington Dollshouse Festival and I'm sure she'll only present high quality:)
So if you're near North Yorkshire in the summer, make a trip. Unfortunately the book isn't available at the moment, but have a look for "Our Dollshouses" from Caroline Hamilton and Jane Fiddick. I hope it'll be for sale when the exhibition starts.
