This great Cover arrived from the far north. Many thanks to Henrik, who send this cover from his latest trip to Svalbard. There are two points to mention on this cover. First the stamp seems to be a personalised issue from Svalbard (from the offical 'Postal Norge'). The second point is the cancel. Its not from the local post office (you can see it here). As I'm told you can ask for the cancel at the local Radisson Blue Hotel. You can try to make your own cover and send a prepared letter to: Radisson Blue Polar Hotel, Box 554, NO-9171, Longyearbyen.
