Bisque porcelain is unglazed white ceramic ware. A popular use for bisque was the manufacture of dolls and figurines. This Snow White set was imported from Japan by the George Borgfeldt Corporation, NYC, circa 1938. Hand-painted.
A couple different sizes were produced. In the smaller set, the dwarf figures measure approximately 2.5" tall and Snow White 3.5".
Dan Alexander of the Dizmentia site has provided us with some close-up shots of the Dopey figure. The piece came from his grandmother's collection which she'd acquired during the movie's initial release in the late 1930s.
Here's a nice shot of the entire set from Major Pepperidge of Gorillas Don't Blog.
And another look from Heritage Auctions.
The dimensions of the smaller box are 5" x 9" x 1.5".
The larger set has a box size of 9.5'' x 17'' x 2.5''. The dwarfs stand approximately 4.875" tall, Snow is 6".
