Hello all, I have been developing an interest in these decanters. I find that they have been made all over the world (at least Europe and America). I have a neat 3-molded pattern one with a neat stopper that I could identify in the McKeren Book. This one looks like one I have seen that came out of the Pittsburg, PA area. I made up my mind to do some more study on them, so any book recommendations appreciated. RED Matthews
