Here is a Cooper’s Beer Ball Tap Knob from the Liebert & Obert Brewing Company located in Philadelphia, PA. This Coopers Beer Ball Tap Knob is in excellent condition for it’s age with only a few light nicks on the porcelain enamel face. This Coopers Beer Ball Tap Knob is probably from between 1938 – 1948 which was the time the brewery was named the Cooper’s Brewing Company.
This ball tap itself would have been used to mark what beer tap was on as well as advertise Cooper’s Beer. In this case it would have been used to tap one of the brewery’s flagship beers call “Cooper’s Old Bohemian Beer”.
