Apart from one catalogue at Pamela's that unfortunately only features drinking glasses, and one book about the company that didn't focus exclusively on their products, I've never found any P&P catalogues - unfortunately.
I think the vase looks German.
Given the fact that there were many German glashuette that produced vases of similar design, I wouldn't put P&P on it without an etchmark. Only very few of them come with a paper label only (in my collection of 30+ only 3 were un-etched). There are plenty of alternatives: Nachtmann, Warmensteinach, WMF, Hirschberg, etc. Some that I really thought were German turned out to be Scandinavian or Brittish...
