Postcards and letters to and from serving soldiers were free of postal charges throughout WWI. Here, a Feldpostkonduktor (a field-post officer in charge of transport of mail to and from the Front) at the military base post office (Etappenpostamt) no. 176 in Galicia (Southern Poland) has sent a postcard to the Post Office Director of Triest, Kustenland (now Trieste in Italy). The card has an example of a dated Hungarian style numbered field post office cancellation (Hadtáp-Postahivatal No. 125) of 7 March 1917, as well as an inverted two-line cachet in violet ink of the ‘K.u.k.Mobiles Etappen/POSTAMT No. 125’.
