Here is a Duquesne Beer Sign from the Duquesne Brewing Company located in Pittsburgh, PA. This Duquesne Beer Sign is from the 1930s era and is in very good condition considering how old it is.
This sign is approximately 13″ by 6″ and is made of embossed metal wrapped on a cardboard backer. This sign was made by the Donaldson Art Sign Company located in Covington, KY; it also still bares the “Display Purpose” sticker on the back too. Signs like this one would have been displayed on the wall or on the bar back of a tavern to advertise Duquesne products was on draught / tap at the establishment.
