There's an interesting copyright statement in this DIY Rietveld furniture guide that Artikel 16b of the Netherland's Auteurswet allows individuals to make personal copies of the designs for their own use, but not sell or transfer the physical chairs to others.
@th I've seen copies of the topright corner chair a few times in second hand shop. I think one is for sale in a shop in Amsterdam north at the moment. clear copyright violation. :)
