Dimi, photo of this mark was taken from
this book - a truly amazing work of art: exact
sketches of thousands of glass markings, labels and signatures - and neither images of markings nor photos of glasses representing the names.
Impossible to post a
short biography - 200+ years of glassmaking (and other industry), plenty of generations all named
Josef Riedel and several plants in different places in Bohemia until 1945.
Polaun is German transcription of Polubný
