Unfranked postcard 23 July 1917 sent to 'Billetmrk' at the Kiosk at Kongens Nytorv. The official postal service postmark 'KJØBENHAVN B. 23.7.1917 3-4E B' and unfranked, then delivered to Telefonkiosken at Kongens Nytorv who must have paid the the postage. 5 øre blue (DAKA 1) 1896 first issue, postmarked with violet numeral 'TELEFONKIOSKEN / 1 / KONGENS NYTORV'. When collected the 5 øre stamp was paid by the addressee, although it is not explainable why the letter has not been charged due by the regular postal service. Extremely rare card.
