This striking French semi-postal stamp features the historic coat of arms of Chambéry, capital of the Savoy region. The bold heraldic shield topped with fortress towers symbolizes the medieval defensive heritage of the city and its strategic Alpine importance. Issued during the wartime period, the additional 60c surtax was used for public or relief funding, making it historically significant beyond postal use. The engraved monochrome design reflects classic French typographic precision of the 1940s regional arms series. A desirable collectible for specialists in French local issues, heraldry, and WWII-era postal history.
