Frandsen of Denmark vintage 1970s floor lamp

This vintage 1970s Frandsen of Denmark floor lamp stands 140cm tall and has a very heavy weighted base in black (diameter 22.5cm), a chrome stem and a satin-finished brushed aluminium tube-shaped head (length 22cm and diameter 8cm). The fitting that attaches the head to the stem has a ball-and-socket joint which allows the tube to be rotated to more or less any angle in any plane. An on/off switch is recessed inside the top of the tube. The lamp takes an Edison screw fitting bulb max 60w and has a European-style two-pin electric plug.
