Tracy, Pauly is a company with a long, changing history in Murano. I have read a bit about them, but have not sorted it all. Could you show us a picture of the vases and labels? I suspect from your description of the green label that it is mid-century. From what I've read, many glassmakers made glass for Pauly and Pauly also made some of its own. I've had a few pieces over the years with a Pauly label, but I have not been able to say for sure who made them. I just call them Pauly glass without trying to go further. If you show us the covered vases, someone may have some idea.
