This is a German military field post card (Feldpost) sent in 1916 from Berzischken (now Beržiškiai, Lithuania). The cancellation of Berzischken is rarely seen on a cover or postcard, this is the only one I have and have seen in my life so far. According to Michel (Memel section of Michel Deutschland Spezial), this Berzischken postmark ceases to exist on the 28th of February 1923, a month after the takeover of Memelgebiet by the Lithuanians and from an information of another source, on 1924, the post office itself ceases to exist.
