Original Panorama-Style Montage View of Washington, D.C., ca. 1914. These images were taken from the Washington Monument, and perform nearly a 360-degree perspective of the city. The major and obvious clue for the date of these photos is the Lincoln Memorial--rather, where the Lincoln Memorial would be. Photo #2 shows the beginning of construction, which began in 1914 and which would take until 1922 to complete. Each is 80x135mm, or 80x1145 mm all together, or 3.25" x 38.5" (actually, about 30" long once overlap is considered).
