Fishing boats waiting for the tide, Port of Havre, sunrise

Callow travelled to Rome in 1876, and Venice in 1877, and this watercolour must have been made during the journey to or from one of those tours. He exhibited 12 watercolours at the Society of Painters in Watercolours in the summer of 1877 - all European subjects including views in Germany, Italy and France.
This drawing was probably inspired by J.M.W. Turner's view of Havre in his set of views of the Lower Seine, first published as Turner's Annual Tour in 1834.
