M, I will try to get you a better picture as this was taken in a very small shop without proper lighting. They are lovely and the dealer bought they a while back and does'nt know what they are but came as a pair. Base is plain smooth and no marks on the entire piece.
Sue, they don't seem to be chess pieces as the face of a man is recognisable while on the other one can barely make out its a woman save for the hair.
I somehow got a feel of boda glass to the touch, same smoothness and clarity of the glass piece. Problem is that the dealer feels the pair has significance and is quoting 75 dollars and I just bought a lovely pair of angelfish (murano, v nason) for 50 dollars.
