Astrid, great piece! I would think that the Oliva attribution is correct -- but wait what the experts say...
If the vase comes from ebay, I have seen it too, and was quite tempted to bid on it (but decided to go for the Ichendorf piece)
I can only show two new purchases (nice, but nothing spectacular):
- small Jaroslav Beranek "Andromeda" vase, 12.5 cm high
- Emanuel Beranek vase, 23 cm high (I guess PN 5987, though the hole is in the wrong place)
And I have to admit that I suffered a severe attack of jealousy today when I browsed through David's gallery and saw his new Vizner vase
