Amber-coloured Prickly Ash Bitters Co bottle. Tooled top.
I thought they were pretty common as I've seen a couple, but e-bay showed only 2 (one current, one ended in the past month).
Was it worth 20 dollars?
They are rather common or perhaps better said, available. One can acquire one pretty much any time one wants one. In my opinion $20 is about the going rate. That one appears to be a little bit above average in color.
