Excerpt from Posten's circular of 10 May 1992: "In order for the market not to perceive these products as official Posten products - available to everyone - and to be cataloged in the next step as a collection product from Norwegian Post, it is important that they are given a design which clearly differentiates them from Posten's collection products."
