This iridescent black textured stained glass parlor kaleidoscope is made from stained glass by Bob Ade. What a statement this beautiful piece of art would make in your office. The overall dimensions are; 9" tall, the barrel is 9 1/2" long, a little over 2" in diameter. The base is 5 1/4" long and 4 1/4" wide. The cell end is a separate turning piece from the barrel, making viewing very easy. The interior has a 2 mirror system that looks into an oil filled cell. This is one great scope!! Polorized images.
