As you can tell by the stitched banding at the top and bottom of the shade this shade also dates to 1930-1931. It is a large shade being 20 1/2 inches at the bottom. It was also designed for the 1250 or 1251 bird cage floor lamps, and in fact, happens to be adorning one in this photo. If you want to see more of the shade, and the lamp, go to the floor lamps section in the photo gallery.
Something quite unique about this particular shade however is that the design consists entirely of crystalline beads! If you look closely you can see the texture that the beads create on the parchment shade. The beads were glued to the shade to create the design.
Oh, and one other thing about Aladdin's "Aladdinite" parchment shades such as this one, they are opaque, and actually pass very little light. The shade will light with a soft glow that enhances the design, but very little light actually passes through the shade to light up a room. In fact all the parchment shades made by Aladdin from 1928 to 1932 are opaque. When Whip-o-Lite was invented in 1933 the new shades were translucent and able to pass most of the light produced by the lamp for the first time. The Whip-o-Lite shades being able to do so was a huge selling point used by Aladdin.
