'Feldpost' letter and postcard

This is a nice original set consisting of a 'Feldpost'letter with envelope and a postcard, both sent by the same soldier. The postcard is marked with Feldpostnummer 27344, indicating that he was a member of the 'Stab u. 1.-5. Kompanie Feldersatz-Bataillon VI/6'. The letter with envelope is marked with '4. (M.G.)Kp.I.Er.Btl. 453'. Nice set of 'Feldpost' letters!
