USS Columbia Stern and Triple-Screw Propellers in Dry Dock, Philadelphia (Unmounted, Faded Photograph)
The original, unmounted source photograph for the album page captioned 'The Columbia in Dry Dock at Philadelphia -- Showing her Powerful Triple Screws.' Though considerably faded with age, the image still clearly documents USS Columbia's distinctive triple-screw propulsion system while the cruiser was in dry dock at the Philadelphia Navy Yard in the early twentieth century.
