Extremely rare oortrait photo of Hans-Joachim Marseille. It shows him wearing this German Cross in Gold as well as the Oak Leaf and Swords to his Knight’s Cross.

In our opinion, the signature is period time stamped (facsimile). 

Hans-Joachim Marseille was a German Luftwaffe fighter pilot and flying ace during World War II. He is noted for his aerial battles during the North African Campaign and his Bohemian lifestyle. One of the most successful fighter pilots, he was nicknamed the "Star of Africa". Marseille claimed all but seven of his 158 victories against the British Commonwealth's Desert Air Force over North Africa, flying the Messerschmitt Bf 109 fighter for his entire combat career. No other pilot claimed as many Western Allied aircraft as Marseille.
