In 1997 the Dutch Employers' Organisation VNO-NCW wanted a Gift for their business-relations and they

asked me to invent something that could be associated to their Organisation. The outside look of the building  'De MALIETOREN', that houses the Organisation did give the inspiration for a Tangram-puzzle that looked alike.

The puzzle was manufactured by Sjaak Griffioen in 2 ways, one in wood and one in perspex.
