Rare Dutch Floor Lamp 1950s

Rare minimalist floor lamp, most likely manufactured by the small lighting company van doorn in the 1950s. I've never seen this model before, probably made in very small numbers. It has a black metal stand which is mostly coated in creamy yellow. The black aluminum shade is nicely repainted in its original colour. It has perforations that gives a nice light effect when lit. The on/off switch is on top of the shade. Unique lamp with a beautiful appearance. The lamp is in very good condition. A few tiny damages on the coating.
