Hellenismos, BTW
For me, the most amazing dollhouse is the Colleen Moore Fairy Castle, it's on display at Chicago's Museum of Science & Industry. Colleen Moore was a famous silent movie star and absolutely loved, loved, loved dollhouses. She had a set designer and 100 workers build this castle and the beauty of it is much of it works; actual books with complete texts, running faucets, playable instruments. I don't know how much she spent to build it but, as you can imagine, it's worth several millions of dollars today.
