Dutch modernist metal wall unit from the 1950s.
Unfortunately I don't know the designer nor the manufacturer, most likely an early design by Coen de Vries for his own company Devo.
I've never seen this particular wall unit before, so it is quite rare.
It consist of 2 cabinets with black and white sliding doors, 2 shelves in blue and yellow, 1 perforated shelf/basket in blue, a black shelf with 2 drawers in red and yellow and 4 black brackets, 2 with a hight of 96cm and 2 of 51cm.
The unit is adjustable, you can compose it however you want.
It is in good original condition, some normal traces of wear due to time and usage.
