I posted this lovely piece on a FB glass group and someone suggested it was likely French, but I didn't get any further on an attribution then that.
It's signed with two larger intertwined letters within a circle, (I'm not sure what the two larger intertwined letters are), and underneath the larger letters it says "CRISTAL".
It's a larger piece, the dancer is frosted glass (possibly is Josephine Baker?), and she fits into the crystal base.
TIA,
Brian
