Superb triple glass mushroom lamp, composed of an ovoid foot on a heel with a curved collar and a shouldered conical cap. Finely acid-engraved cameo decoration of a lake landscape, with black trees and groves in the foreground, on the intermediate layer in the background turquoise blue vegetation, all on a white and ocher marmoreal background. Perfect original condition, hammered wrought iron support claw, superb luminous effect both on and off, electrification refurbished by us.
