Art Deco Black Bakelite Box
A circular, streamlined, bakelite box, made in the 1930's. It was made by the American Insulator Corporation, and used either as a cigarette or jewelry box. (This information was discovered in an old plastic's advertisement).
It can also be seen on page 42 of the Keresztury's book, "Art Deco Bakelite and Jewelry Boxes." I also have this same box in a dark brown bakelite.
