This is the Loetz Argentan decor in violet. An extremely complicated paperweight decor that is cased within layers of glass. Tiffany and their famous Paperweight line did similar work. The burst foil contained within the layers is a hallmark of this decor. On top of that, it was designed by one of the premier artists at Loetz, Leopold Bauer in a documented form #4243 as shown. Decorated in several panels of burst foil, a design feature that would surface again in Murano Italy many years later.
The rim is factory fire polished and the pontil is ground and polished as expected. It stands a bit over 5" tall and is in excellent, as made condition without issue.
