A 12x10 negative. A slightly distant starboard side view, taken from ahead of the beam, of the screw tug Thistle (1891) at anchor in Gravesend Reach, River Thames. Four crew members are staing on the fore deck. The tug is flying her owner's house flag. Tilbury Fort Watergate is in the background. The negative is cracked horizontally right across but a 12x10 photographic print made before the damage is available for scanning. Negative number P8538 is a half plate copy of this image.
