Looks exactly like mine (which certainly is neither lead crystal nor hand-cut)
Michael, if you want it to be lead crystal and hand cut, I could give you a label for it. Or, I could give you the label and you could begin a lovely 'mislabeled' collection.

I'm glad it really is what I thought it was. By the way, how tiny is the Viznerova piece in comparison to the 20053? This piece is small enough -- I can't imagine a vase being much smaller.
Rosie, thankfully I didn't pay a huge fortune. I won it for 5zl, so with postage I paid a total of 11zl. I suppose it's a fair enough price for the piece. I will still write to the seller though, and politely inform him of the damage which was hidden behind the label. Maybe he'll return a portion of my money.
Thank you for your comments!
