I'm not usually a great fan of this sort of engraved glass but I think these stylised fronds are quite attractive. I'm guessing it's 1930s, European?
If it's any help, the cutting seems very finely done with each leaf and rectangle filled with very fine lines, giving them an almost textured appearance. It glows very strongly, has numerous air bubbles and a couple of very small black inclusions.
Thanks for any ideas.
