This is one of 262 drawings and 2 paintings presented to the Museum by the artist's family in 2012, and related to John Kingsley Cook's wartime service in the merchant navy between December 1940 and August 1945. Cook left Cardiff on board the 'Royal Crown' in late December 1940, and drew Milford Haven on this first trip. This sketch was drawn on the back of a fragment of a a small scale British Admiralty chart showing the Northwest Coast of Australia. This is the bottom left corner of the chart, which includes lines of magnetic variation. Fragment appears to be from the same chart as ZBA5433.
