I was contacted by PostNord in December of 2014. They told me that they were planning to release a series of international stamps on the theme of the Northern Lights. They had been in contact with Rymdstyrelsen, the Swedish National Space Board, who told PostNord about my work. The selection process and the design has been going on during 2015 and now the stamps are ready for publication on November 10, 2016.
Here are all five stamps that are being released.
