On January 2, 1999 Norway Post will also issue two self adhesive stamps celebrating Norwegian inventiveness. The cheese slicer (Kr 3,60) and the paper clip ( Kr 4,00). These inventions have been of great significance both in Norway and abroad Especially the paper clip is an invention that many of us use every day, without thinking of where this invention is coming from. These stamps are printed in photogravure by Joh. Enschedé in Holland, and are issued in Rolls of each 100 stamps.
