Sweden. Military cover The Swedish Åland Demolition Detachement 1919. A nice postcard with 2×10 öre postage with cancel "ÖREBRO" 31.7.19 nice mounted on page to a Swedish 2nd Lieutenant at the Swedish Detachement at Åland. Also written in the address "Mariehamn, Åland" which is rarely seen and also postcard is more rare than a cover. Good quality and exhibition item!
