Daum Cameo Glass Lamp

Hello: I bought this lamp in Williamsburg, VA about 16 years ago from a well-respected antique dealer / appraiser. It was presented as an unknown/unsigned cameo glass lamp. I felt that this was a very high-quality lamp and had a hunch that a lamp of this quality might indeed have some form of identification. I purchased the lamp and paid a good price. At home, upon closer examination,I loosened the keeper nut under the metal base and rotated the glass. There are three paws that cradle the glass and the now visible glass area, to my joy, presented me with an impressed signature "Daum, Nancy". Needless to say, I was extremely happy with my purchase. I don't think that this lamp ever had a glass shade and had this shade custom-made with old Victorian material. Regards.
