Here is a Pabst On Draft Sign from the Pabst Brewing Company located in Milwaukee, WI. This Pabst Blue Ribbon On Draft Sign dates from the 1940s era and is in excellent condition considering how old it is.
This sign was made by the Permanent Sign & Display Company located in Reading, PA. It is approximately 14″ by 7″ and is made of celluloid-over-tin wrapped on a cardboard backer. Signs like these would have been hung inside of taverns above the tap system to advertise Pabst to patrons.
