You see mine are empty too.Nice collection.
I had a couple, a pair of moccasins and a cat. I sold the moccasins and still have the cat pipe holder. I don't display my pipes, I keep them all in drawers in my pipe/ tobacco cabinet.
I don’t collect them but seem to keep buying them (and then filling them with new pipes ).I just grab one when the mood strikes and the price is right. They are getting are to find. Oh and not a duplicate of course.
