My wife and I have browsed the Thorne Miniature Rooms at the Art Institute of Chicago on previous occasions. But after seeing the display of the Thorne collection at the Phoenix Art Museum during our recent two-week vacation in Arizona, we decided to make another visit to larger Thorne collection in Chicago. It is an exhibit unlike any other, a child's dream. Thorne Miniature Rooms are a set of about 100 miniature models of rooms created between 1932 and 1940 under the direction of Narcissa Niblack Thorne, who was born in 1882 in Vincennes, Indiana. As a child, she began to collect miniature furniture and household accessories. Her uncle, a U.S. Navy vice admiral, sent her many antique dollhouse miniatures from around the world. When she was 19, she married Montgomery Ward department store heir James Ward Thorne, whose fortune helped to finance her hobby. Ninety-nine of the rooms are still believed to be in existence. The majority of them, a total of 68, are on display at the Art Institute of Chicago, located at 111 South Michigan Avenue. We saw 20 of them at the Phoenix Art Museum. The Art Institute's rooms document European and American interiors from the late 13th century to the 1930s and the 17th century to the 1930s, respectively. Constructed on a 1:12 scale, the rooms are largely made of the same materials as full-sized rooms and some even include original works of art, including paintings and sculpture, silver bowls and crystal chandeliers. They are among the most popular attractions at the Art Institute with an authentic appearance and attention to detail that boggles the mind.
