Okay, if you were browsing the site from the beginning you saw this style previously. That shade was the No. 218 green Whip-o-Lite shade. This is the same style only it's the No. 217-tan shade.

There are four design numbers for this style of shade: No. 217-tan shown here, No. 218-green shown in this section as well, No. 219-rose (not shown), and No. 220-white (not shown). All four designs (colors) were shown in the 1937 advertising brochure for Aladdin Whip-o-Lite shades.
