Thank you, Kevin, for posting those photos.
I have a couple of questions, these pokals are colored glass, but they are also cut and they ring like leaded glass. How was the color added? It appears to be the color of the glass, not a surface coat. Does the coloring of the glass date them in any way? The etched and cut bands are clear.
I have two, and although they are very similar they are different, one thicker, one with a blunt point on top, the incised/cut decorations are different sizes and different distances apart, etc.
