This sheet -metal wall lamp has affinity with some Le Corbusier  creation , In 1949, he  conceived   a wall lamp of metal sheet to enlighten the entrances of the Unité d’Habitation in Marseille, followed by different version .
This piece is definitely inspired or possibly part of some of multiple creation . I can be fitted on a wall or left on the base to become a desk lamp.The 2  last picture are reference found online .
H.17 in x w.19 in x D.20 in , rewired  with US standard socket  , stripped to the metal.
