This beautiful, topaz yellow elegant glass plate was produced by Cambridge Glass circa 1930s and is marked on the bottom with their C in a Triangle mark. The piece is part of their Keyhole pattern and has a handle on either side in the classic Keyhole shape.
This piece measures 6 3/4" long and 6" wide. It's got a depression in the center so I think it might be an under plate for a mayonnaise bowl or something similar. The rim of the plate sits 3/4" above the tabletop.
This piece is in excellent condition. It has a little very light wear from age and no chips, nicks or cracks at all.
