I bought these (4) as part of a lot at a local auction.  I was hoping that I would find a mark to identify them, but no luck.

These pieces are very pretty.

They have engraving/etches (I never know the difference) and cuts.  The decorations extend from the bowl, down the stem and on to the base.

The glass is thin and there is a nice shape.

I would like to identify these pieces.  So…if anyone knows, please share!
