I can tell you how rare this lamp is because I've never owned nor seen another example before in 50 years. It's Art Nouveau with twisted vines and four beautifully matched green pulled feather tulip shades. The base has a magnificent original patina. Each of the shades are signed, as well as the base. You can't tell from the photo, but this is a large lamp, 29¼" tall and professionally rewired. It's fabulous and ready to go into your home!
