Field Service Army Postcard Dated 19th January 1918

It was realised that careless talk costs lives even during the First World War. So, in order to simplify the censorship process, these buff coloured Field Service Post Cards were used. This card was sent from Egypt on the 19th of January 1918.

Wonder if the copyright still applies..? Students could find a box of these useful, especially if the address sides were already filled in.
