I made this shade many years ago as a gift to my mother. She passed away and so now I have it. It is a copy of the Tiffany 16" pansy, but not from a kit. The background glass is a common Bullseye glass. The flower glass is mostly Uroboros standard colors from a few decades ago. It has a standard 4" ring that can be used on any base (shown here on a common stick base reproduction.) This shade is for sale for $1000.
