From the Star-Spangled Banner flag to Dorothy's Ruby Slippers, the Smithsonian Institution's National Museum of American History is home to some fascinating objects. In fact, one of the most fascinating of these, and one of the most popular, is itself a home. On the museum's third floor sits a five-story dollhouse donated to the museum by Faith Bradford, a Washington D.C. librarian, who spent more than a half-century accumulating and constructing the 1,354 miniatures that fill its 23 intricately detailed rooms.
