Could someone help with German writing please?

Hi, I have a postcard with a photograph of a German WWI soldier on it, it has not been posted but has some writing on the reverse, could some one be able to translate it please, I am wondering if it gives any clue as to the person on the front.

Just to add, he is not a ancestor, the postcard is one of a number I have showing soldiers from the Great War.
Any help as always would be very gratefully received.

Many thanks and, as always my very best regards.

Frank.
