This Norwegian official postage stamp, denominated 40 øre, features the crowned national coat of arms with the Norwegian Lion holding an axe. Issued for government and administrative use, the inscription "OFF. SAK" (abbreviation of Offentlig Sak, meaning “Official Matter”) distinguishes it from regular postal issues. Printed in dark olive green with a clean, bold design, the stamp reflects Norway’s long tradition of official service mail. Such issues were not available to the general public and remain a specialized field for collectors interested in Nordic postal history.
