I've been watching this wonderful vintage house on German eBay (currently 204 Euros!) and have noticed with interest how the price has been steadily increasing over the past few days. From the stenciling on the side, it looks like it is "Haus Carmen," and resembles the house styles on this page of the Puppenhaus Museum website. All quite lovely!
The window hanging below resembles one on this page of the Puppenhaus website.

UPDATE, 12/3/09: The auction ended after 102 bids (!) at a healthy sale price of 697.67 Euros! That's about $1,052 in USD! Wow!
