I took my photos to the antique show we have once a month and went to the booth that sells lamps. The gentleman told me it’s a GWTW style and since handpainted and signed it could be well worth over $1K, especially from famous artist. That artist signature is on the inside of the top globe. I had someone point me to a website last night to check various things on it. After doing what the website said I believe that it’s not as valuable as the gentleman at the antique show led me to believe and dropped my price substantially. I am curious about it being signed though and I haven’t seen another one like it??? If you go to the link Sophie provided above u can see much better pics of it.
