I found this vintage exit light from the 1930s

I don't know where we got this old glass light shade, but I know I like it.  I didn't know anything about it so I did a little research...

Modernistic vintage 1930s Wedge Exit Light by Kopp Glass

Here is the original 1938 catalog page at the Vintage Ads and Books website featuring this wall-mounted wedge-shaped glass exit light.

Here is another old catalog page for sale showing a Kopp wall mounted exit light. 

Our light is stamped "KOPP" on the back.

A little history of the company and its founder, Nicholas Kopp...

A chemist, Nicholas Kopp, trademarked a mixture for a vibrant red glass in the 1890s. [Pittsburgh Post-Gazette]
Before the turn of the last century, he worked for Hobbs Glass Company, then for the famous Fostoria Lamp and Shade Company where his father, Nicholas Kopp, Sr also worked.  When Consolidated Lamp and Glass Company bought out Fostoria, he went to work with them.  Consolidated is the company that produced the highly collectible Ruba Rombic Art Deco line of glassware.
[The Antiquarian]

In 1900, Kopp struck out on his own, founding the Kopp Lamp and Glass Company and began manufacturing lamps.

[He] took on new partners a year later and renamed the business Pittsburgh Lamp, Brass and Glass Co., or Pilabrasgo for short. It specialized in lamps and lighting.  The bright red glass that Kopp formulated found a market in the railroad industry for signal lights. Union Switch & Signal, a railroad products company begun by George Westinghouse in Swissvale [PA], was likely an early customer.  Pilabrasgo, however, went bankrupt in 1926 and Kopp reorganized the company with [Charles] Curry, again naming it [Kopp Glass, Inc.] Railroad signal lenses, light fixtures, lamps and vases were the core of the business.       From this newspaper article in the Pittsburgh Post-Gazette in 2002

This rebirth of Kopp Glass is still in business today making industrial and technical glass.

Back in the day, Kopp also produced gorgeous modernistic glass ceiling globe shades like this one:
