This is a very pleasing large format photograph of Oberstleutnant Friedrich Ritter von Haack. Von Haack was a Bavarian who was assigned to the General Staff of the Bavarian I. Armeekorps. His award of the coveted Orden Pour le Mérite (PLM) came on 4 August 1918 for his planning while on the General Staff. He is wearing the PLM in the photo. His signature and personalization appear on the photo’s reverse. This photo was taken shortly after his award. The personalization was dated 30 August 1918, a mere twenty-six days after his award. Von Haack was also awarded the Knights Cross of the Bavarian Military Max Joseph in April 1918, which carried with it an automatic elevation to knighthood. This is a very fine photograph and personalization to a man who won the highest military awards that both Prussia and Bavaria could offer.
