Can anyone tell me about this metal Sculpture? Could it be a C Jeve?  

This floor lamp was purchased by a family member about 20 years ago at a local antique shop that dealt with mid-century. I have finally ended up with it and would love to know something about it. It looks to be a C Jere piece but with it being such a large piece (it took me over an hour just to dust it) I have no idea where to look for any identifying marks. The lamp stands 6 feet tall and is really heavy. Brass with a beautiful patina. The shade is not removable.
