Wall lamp in rattan from the 50

Superb rattan wall lamp in arcs of a circle, with a thin sheet of paper or white cardboard inside. 50s and 60s, pure Scandinavian style! Old electrical system but which may have been modified once (two electrical cables of different colors). Untested, sold in the state. Very good general condition (see photos). Note: one of the three stems supporting the nerve has unsoured and at the back, at the double circle, the wood has been somewhat split (probably by a nail)
