Italian, second half of 20th century. 1960's Achille and Pier Giacomo Castiglioni ARCO floor lamp for FLOS. The base of the lamp is a white marble parallelepiped with rounded corners. A hole runs through the center serving to fix the vertical stem supporting the curved stem of the lamp and also provides a space to insert, for example, a broomstick so the lamp can be easily moved. The arched stem is made of three pieces of stainless steel which can telescope one into the other, concealing the wiring. The reflector is made of two pieces: a fixed dome, perforated to facilitate cooling the socket and a swiveling aluminum ring on the dome for adjusting the position of the reflector.

Missing 2 connectors. Vertical scratch on marble base located on the right side measuring 6.5 inches. There is wear to the interior of the ball shade. Electric cord is frayed and wrapped in black tape.
