Italian floor lamp composed of dual shade (interior white and exterior light plum acrylic shade) mounted to a nickel plated steel rod on an enameled steel base. Shade height adjustability via a 'push-button' mechanism, allowing the shade to be raised or lowered effortlessly along the full length of the stem. Often attributed to Gino Sarfatti for Arteluce, but unmarked. Base diameter 11" Nice patina to the stem / base and minor wear commensurate with age, but in overall excellent, original condition.
