American art deco green glazed ceramic and metal humidifier.Circa 1939.This example is made by ‘Walton’ and is in working order – I have used it but should have an overhaul.The ceramic bottom and painted metal top are in a wonderful eau-de-nil green.The maker’s transfer is wearing off on the front and there is some corrosion around the ‘mister’ at the top, but otherwise this very rare piece is in great condition.16” in diameter 12” high.
