Articulated wall lamp space age vintage 1960

Correct state. The dark blue half-sphere is made of metal and has stripes and a pok: see photos. Oxidation at the hinge of the chromed metal arm. The other parts are in excellent condition, the wall lamp seems to have never been installed. Rotating the upper part of the blue half-sphere allows you to adjust the lower shutter and thus vary the light. Works (porcelain socket). Depth about 65 cm. Length (diameter of the ball) 24 cm. Height 25 cm. Very beautiful design, a quite extraordinary wall lamp.
