Library lamp, art deco reading light from the 20s

Library Lamp, Art Deco Reading Lamp Year 20. Uncommon model, it is a reading lamp. It is placed on a shelf or a high piece of furniture and is directed to read. It is heavy so that it can remain still when directed. It can of course be used as an accent or bedside lamp. It is made of tinned metal, aluminum lampshade. Good condition except for wear and tear from use and time, oxidation of the tin (see photos) The twisted cable is original, I kept it because it is in good condition but I changed the switch and the plug. Dim: H: 25.5 cm L: 39 cm W: 13 cm.
