This one belongs to my father, he always thought it was made by Pallme Koenig but I am not so sure.
I have not been able to match the shape but the decor looks very much like Kralik Pampas (rather then Loetz Pampas). The vase has a cut and polished rim and is 22cm high. I am fairly sure the body is in clear glass - it is the iridescence that gives it that greenish tone.
Any ideas?
