Then we've got this cartoon from Punch. Dunsany liked huntin', shootin' and fishin', and was often gadding off to Scotland, where Sime lived in his early thirties, to pursue these leisure interests. However, I think this predates their first meeting.
Lastly a portrait in oils of Miss Mary Susan Pickett. In 1898, at the age of 33, Sime was studying watercolours in South Kensington. A reflected face appeared in the glass of a dark picture. She was a painter too. He asked to borrow a tube of lamp-black that he didn't need. That year they married in Edinburgh, and were together until Sime's death in 1941.
