Chicago's Museum of Science and Industry holds a delicate treasure: Colleen Moore's Fairy Castle. Moore was best known as a successful film actress whose career began in the silent era but later transitioned into talking pictures. A lifelong fan of dolls and doll houses, she commissioned this elaborate tiny house in 1928, for a total cost of nearly $500,000—in 2019 money, it's estimated to be worth $7 million. By 1935, approximately 100 craftspeople had worked on the Fairy Castle, according to the museum. No detail was too small to include.
