Here is a Graupner’s Beer Ball Tap Knob from the Robert H. Graupner Brewing Company located in Harrisburg, PA. This Graupner’s Beer Tap Knob is from the 1940’s era and is in excellent condition considering how old it is.
This beer ball tap knob is made of an etched and painted copper face mounted in a bakelite black body. There are actually 2 variations of this Graupner ball tap knob, one like the one pictured here and the other reading “Graupner Old German”; click here to view the other variation. I am actively looking for the other variation to add to my collection.
