Not sure whether this is going to help or not, but ...
According to the Great Glass site, it seems that Kralik made some pieces with that mould-blown texture and in a similar pearl irridescence, but those pieces also have green trails of various sorts (applied trail rim, peacock feather decor, etc). Apart from that, the shape looks very boho. I do know that the texture on your piece looks very like the texture on mine, which is almost identical to one on the Great Glass site (
www.great-glass.co.uk). Doesn't necessarily prove anything, though.
Leni, what pages of Gulliver are you looking at? (And isn't it just the most fantastic book!)
Maybe Marinka can help!
(I just knocked a Krosno sherry glass off my desk, and caught it on the way down! Not bad after downing the contents...)
