Featured How old are these place card holders I found at goodwill

They were in a taped-up plastic bag marked $1.99. I couldn't tell what they were or condition till I got them to the car. There is eight of them. One has a large chip, but the rest are in great condition.
Can someone tell me how old they are? made of Brass and intaglio glass.

I’d think twenties, the intaglio glass may be Bohemian.

 

They're not going to be earlier than the 1920s because of the skirt lengths. But without a close-up photograph...

Natural waist lines. Maybe 1930s.

There are so many of these on ebay. Some were done with colored glass. All appear to be in very good condition, same as yours..

The anatomy of the 3 dancers is definitely odd. Even for "swing" dance..

 

'Spect they're meant to be the Three Muses.

Yes there are lots of them out there. 1930s sounds about right, maybe a little earlier. It's just that the varying descriptions had me wondering age.
Thank you all very much.

The construction says they're legitimately old, and not 80s or later repop.

 

Debora beat me to it. Three graces or three muses. Ancient images.
