A slightly distant stern view, taken from fine off the port quarter, of the Royal Navy battleshipIron Duke (1912) at anchor in the Thames Estuary. She is the flagship of the C-in-C home Fleet and has accommodation ladders and boat booms rigged on both sides of the ship. Her quarterdeck is fully enclosed by awnings. Two steam pinnaces are on the right of the picture. The negative is very slightly unsharp.
