I would willingly admit that my knowledge on continental art nouveau and art deco glass is poor. So I need some help to put my mind at rest. Who made this stunning piece of iridescent glass. Over I have bought quite a few pieces of iridescent of lustre glass and when confronted with the opinion of the "expert glass dealers" I often get 2 or 3 different makes or "well it's errrr Czech mate"type answers.
Any ideas ? not Loetz, perhaps Kralik, Rindskoft, Pallme Konig or ?
