Insufficiently franked 10 øre Postcard sent from Trondhjem via Leith to Reykjavik. Charged 20 øre due, for which amount a Two Kings 20 aur (1907) stamp were affixed in Reykjavik and tied by “Reykjavik 11.11.09” CDS. Iceland did not have any postage due stamps and instead ordinary stamps were used instead, and these usages are quite scarce.
