Interesting vintage Wine glasses with a bottle stoppers

Hi,
I got these pretty cool wine glasses with a stopper base ? I've never seen a glass like this before, and now I've seen two.
Both got chips but lucky for me to find them whole.
The small one is really delicate and light with a great etching, the bigger one is heavy and thick and has a simple etching. Im not sure how old they, I would guess the turn of the Century ?

Let me know if you have seen theses before. Thanks for looking
