Does anyone know the designer of this Farstrup Chairs and Table set ?  

Do you mean payments to the designers?

Yes.

Generally the Danish designers were paid on royalties, so how much to paid depended on how well designs sold. I believe hat the best selling designers were not poor.

Ah, thank you. So from that point of view it totally makes sense that architects would draw similar designs for different companies if the designs had sold well before. And it also would make sense for companies to use inhouse designs in order to avoid the payment of royalties.

Having said that, I suppose that for instance FDB would have had an interest economical wise to prevent Farstrup from producing something so similar to their own top seller. Is anything known about law suits over design and copy rights in Denmark?

I remember reading that Danish laws at the time were inadequate to protect furniture designs.

Thanks. Case closed.
