Well! Believe it, or not, this is not a Bohemian Tango glass! It is a Pairpoint #B-228 Flambeau & Black Amethist tazza. Pairpoint never applied a clear overlay to Flambeau. And you will never find bubble balls on a Czech Tango glass. :o)) And yes! The silver decoration is Rockwell! Sold for $1.675,- in 2008.
