This is an ‘Arco’ Floor Lamp, designed by Achille and Pier Giacomo Castiglioni for Flos in Italy in 1962. This piece dates to the 1960s, as evidenced by its perforated diffuser with small holes. Later versions feature larger perforated holes. It has an aluminum shade that pivots, and the steel arm that supports the shade fits into a rectangular Carrara Marble base. It is said that the Castiglioni brothers were inspired by a street light for this design, as they had set out to create an overhead light that did not need to be installed to the ceiling.

The lamp measures 9.5 inches long, 12 inches wide, and is 101.75 inches high at its tallest point. There is patina on the perforated diffuser, and there are some scratches on the post of the piece. The Carrera base has scuffs and scratches. Overall, this lamp is in good original condition. Please see photos.
