Astrid, thank you very much for the hint! This oval shaped one is nice as well, but I will stick with my rectangular one.
I have got already too many areas I collect (Czech, Finnish, Riedel), so German glass will only be bought if I come across a nice piece for a nice price.
BTW, whenever I see the buy-it-now-prizes some ebay sellers ask for their items, I wonder if these really sell? For instance a Jachmann WMF vase for around 200 Euro if I remember correctly, or the Hlava cut vases like the one I posted a few days ago, most around 300 Euro
Dirk, you are right that this particular seller has nice pics.
And funny descriptions: "Massive Fantastische XL Vase"
