Vintage Art Pottery Lamp Pink Iris Flowers Signed David Nelson Cut Out Basket. This is a stunning, handmade pottery vase. It has pink irises carved into it as well as cut outs that look a bit like a basket weave. It is made by David Nelson and signed near the base. I believe it was made in the late 1980s to the early 1990s. It does not include the lightbulb or a shade. There are no chips, cracks, or crazing. Please see the pictures for the full description.
