Beautiful and unique Art Nouveau style lampshade. Unfortunately do not have the base. There are no markings to indicate maker or year. Five of the glass panels are a translucent blue/green mix. One panel is blue only. Unsure if it was replaced or original. Metal is quite thin pliable, and as result, one band became disconnected from the top of the lamp. See photo.
