Kunst + Interieur, a modern antique shop in the centre of The Hague houses some designs by Aldo van den Nieuwelaar. Probably they were his on the moment of his death. Most objects were lamps from the mid seventies.
Last time I visited, I was stopped by this large B/W picture. But that's ...
And I took this iPhone picture. This is how we got to know him in The KABK [Koninklijke Academie van Beeldende Kunsten, in The Hague]
I always state he was one of my 'greatest' teachers. His approach to teaching was new then and is still interesting today. 

Aldo died 23 september 2010 [wiki] still rather young, being born in 1944.

His circular tube lamp, which I bought some time in the late seventies is a iconic classic now.
