Graphical free standing wall unit

This freestanding wall system, likely made in the 1970s in Belgium or the Netherlands, is a rare and high-quality piece.
Its maker is currently unknown, and this is the first time we've encountered this particular graphical  design, suggesting it might be unique. Versatile in use, it can be placed against a wall or serve as a room divider in the center of a space.
