Military mail sent by Franz Mack to his parents showing a picture of Metz supposedly from 20.02.1915:
Last greetings from the fatherland near by the border. This area was the showplace for the first battles.

From the german daily war bulletin from 10.02.1915:
“All quiet, except small achievements for our troops in the forest of Argonne, west of the vosges mountains, at Ban-de-Sapt and in the forest of Hirzbach.”
