Have been lucky to get the so far only known prototype Spy Lamp in red from 1972. If you compare this one and the serial produced version from Louis Poulsen you can see the shade is more transparant than the later serial produced. The lamp itself has a ”spacer” behind it wich makes it ”hoover” out from the wall or ceiling. When I first got the lamp, the parts was mounted the wrong way so it didn’t look like it should. Now the pieces are back in the correct places and the lamp looks fantastic!
