There is a date issue, however, with the photo. There were two battleships named USS Idaho. The first one was a "Great White Fleet"-era battleship that the United States sold to the Hellenic Navy (Greece) in 1914 (and later sunk in 1942 by German bombers). New York Shipbuilding Corporation launched the second battleship named Idaho in 1917, but the U.S. Navy did not commission the ship into the fleet until 1919.
It is possible, given the war crisis at hand, that Idaho conducted part of her shakedown cruise with the rest of the fleet. Any assistance in identifying the photo would be most appreciated. Below are two positive identified photos of the second Idaho battleship.
