Doll figurine table lamp

This lamp was given to us by my mother in law. She mentioned that it was a famous artist' piece and may be worth something. So we are checking it out. It is a figurine or statue of two female dolls. They are both atanding on a rocky surface, one up above the other, and leaning in toward one another and have something in the opposite hand of which they are leaning. The higher up has a basket with possibly flowers and the lower has what lookes like flowers in hand. Also there is a harp i think next to and lower and in front of them. There is a bar that comes up behind the higher girl that has the part of a lamp that hold tge bulb. The lamp is very heavy. It is 41inches from the top of the lamp fixture piece to the base, about 25 from the base to the head of the higher doll, and about 12 inches across with a felt pad enclosing the bottom. There are two stamps and one signature, all in which are hard to make out but i will take pics of them. Thank you.
