No one else has written anything, probably because they are as confused about Pauly & Co. as I am. Pauly has a long history in Murano, sometimes making its own glass but also marketing other companies' glass. I've never been able to get a good handle on Pauly. I wouldn't be surprised if the vase was made by another Murano company. I am thinking of a certain company that does cobalt glass similar to this, but don't want to do anymore public guessing.
