This gorgeous lampshade was made for a special lamp that we know is out there. We took gold pony style metal foil and mounted it on a Paris Oval wire frame and lined it John Darian blue Swallow wallpaper. This serpentine shaped lampshade measures 12in across the top, 15in across the bottom, 10.5 slant, and it has a brass washer spider. It is an opaque lampshade, the light will cast up and down and be a work light (desk lamp), floor swing next to a chair or romance lamp. Anyway you use it, you'll have it for a long time. Quality.
