I recently picked up these two ceramic tap towers from someone on Craigslist. She told me they were removed from a bar here in Minneapolis before it was demolished. Unfortunately, she couldn't remember the name of the bar. I have been trying to do some research about them online but have not been able to find anything. Does anyone out there know how old they are and also what the value of them might be? The brass looks kinda tarnished and i am wondering if i should clean and polish these up. Thanks for the help!
