I'm not quite sure where to put it. I think it's German or somewhere in that region, but I'm not sure about the time period. It has a bit of an art-deco-ish feel to it, I'm not sure how old it is. Anywhere between 1920s and 1960s would be possible? It has some age to it, it's definitely not a new vase. If it's older than 1950s, I hope someone with a bit more knowledge of pre-war glass can help me pin it down somewhat.
The outer finish looks look like it has seen better days (which might indicate it wasn't very high quality to start with?). The decoration is applied in a very thin layer, but that has been scratched away in places. There are lots of signs of use in the interior and at the base. The previous owner said he bought it in Germany, so it might hail from those parts originally.
It's not exactly my normal area of interest, but I liked the striking design, even if the quality wasn't quite there. And because I had a nagging feeling I've seen something similar, but I can't recall where or what or where to begin looking.
It's fairly big, 30 cm high, 13 cm across at the widest point, 5 cm across at the rim itself.
As usual, any speculation on time, origin, factory, etc, is more than welcome,
