• Unknown date, but likely taken around 1910–1916 in the newly independent nation of Norway (which became free from the union with Sweden in 1905).

• Ten members of the Signal Corps are posing with rifle, semaphore flags, spotting scope (both binocular and monocular on a wooden tripods), etc. The men are wearing the dark uniforms of the Norwegian Army from 1894, which were replaced by a mountain-gray field model from 1914 on.

The officer to the right in the background, identifiable by the two stars on his collar, holds the rank of premier lieutenant (Norwegian: premierløytnant). He is most likely Vidkun Quisling (1887–1945), later the leader of the Norwegian Nazi party before and during World War II, as indicated by his resemblance to other portraits of Quisling from this period. Quisling began as a cadet at the military academy in Oslo in 1905, graduated as a lieutenant in 1908, and pursued further education and various military roles, including as a captain and a military attaché in Russia by 1918.
