Here is a Duquesne Pilsener Beer Sign from the Duquesne Brewing Company located in Pittsburgh, PA. This Duquesne Pilsener Beer Sign is from the 1930s era and is in excellent condition considering how old it is.
The sign is approximately 16″ by 8″ and is made of reverse-painted glass mounted in a metal frame with a cardboard backer. The sign was made by the S. S. Zentner & Company located in Beaver, PA. Signs like these would have been hung on the wall or displayed with the cardboard easel back on a bar countertop.
