Architectural iconic 1st edition model Z or Decora desk / table lamp in black metal and brass by Louis Christiaan Kalff for Philips in 1950.The lamp is made of solid brass, with a metal lampshade, refinished lacquered in black .The lamp is impressed with the Philips brand  , and it is in excellent condition for its age .I have other Louis Kalff lamps . 

I’ve owned this lamp and the other lamps which i have listed for the past 40years plus ,from when i first started collecting 20th century design . I have moved into my final house and i am now selling my surplus item's including the lamps which I have collected  over this period .
