From the late 20s to early 30s come this wonderful matching sconce with the "sanitary" look. White on white was thought back then to be what was needed for a clean and sanitary surface.
Both sconce back and shade are in excellent condition with no noticeable chips and no cracks.

The shade is often called Camphor Glass or clam broth in color. One shade has a surface manufacturing mark across it's top as seen in the last image.
