This is a beautiful french walnut dining room table with four chairs. The set features ball and claw table and chair legs with carving at the top of the legs. The table skirt has no carving.
I know nothing about this chair other than what I have already written. Looking closely I can see that the wood of the arms and legs is molded and was originally left its natural color. The upholstery is a green vinyl though I think this is probably not the original covering because there are tacks along the back of it. It is clearly from the art deco/mid-century modern era though that is all that I've been able to determine after many hours spent online reviewing thousands of photos of mid century molded wood armchairs.
