Art Nouveau atomizer perfume bottle, Art Deco, acid-free glass paste

Art nouveau atomizer bottle - art deco. Superb old bottle, either atomizer or vaporizer. It is in paste this double layer glass. Colorless and green. It is conical in shape, resting on a thin heel. It is cleared with acid and shows a green tree. Between a lake and mountains. Decor well in relief but rather diffuse. The mechanism has its inner metal rod. The pear that has been removed is missing. There is no signature but the quality suggests. To a master glassmaker certainly renowned. Total height: 23.5 cm. Diameter: 8 cm. Good condition, no blemish. Beautiful authentic object to collect.
