Letter from Helsingborg to Copenhagen via Helsingør 20 April 1866. On arrival in Helsingør the letter was stamped with the scarce boxed mark “Fra Sverrig” and Helsingør CDS on reverse 21.4.1866 and Copenhagen CDS same day. The postmark was ordered by the Helsingør Postoffice 3 June 1865 and apparently in use from 1 August 1865. Also the rate of 8 sk. charged was the special Øresund border rate.
