Edgar Tarry Adams inside the hull of the Royal Navy battleship Cornwallis (1901), which is in frame on the building berth at the Thames Iron Works shipyard at Blackwall, London. The photographer is inside the hull looking across the bottom frames, showing some of the lower side frames in place. A riveter's portable blower forge is on the left. Sitting in the centre of the picture wearing an Inverness Cape and a hat is Edgar Tarry Adams, who is making an artwork using an artist's portable sketch box on his knee. A note on the vertical format negative says the photographer is using Camera B.
