I bought this recently without much thinking because it had a very similar feel (and similar colour) as a triangular vase I have identified from the Sklo Union CD and older messages on this board as pattern 12996, Vaclav Hanus for Rudolfova (and because it was merely a couple of euros).
The smaller one doesn't have a triangular shape, instead it has 2 sides drawn out, and it doesn't have the indentations at the lower part of the side either, but for the rest I thought it was a variation on that theme (the rim looks certainly similar). However, I can't seem to find this one on the CD, so I might be off. This one is 12 cm high. Base is 4 cm at the narrowest part and 4.5 at the widest. Rim is 9 cm at the widest and 7 cm at the narrowest part.
I put another picture where it's compared to the 12996 (on the left). The colour is also slighty different, so it might be either much more modern, or from different origins entirely.
Any help appreciated...
