This painting of Dr Marshall is typical of military portraits of the period. The formal, dignified pose of the sitter in his Royal Army Medical Corps officer’s uniform communicates status and authority. Wartime privations are deducible from the use of reclaimed, poor quality materials. The portrait is painted on a sheet of hardboard and framed in the carcass of an old picture frame. Painted at a time of war it is interesting to consider this portrait as somehow representing the unusual relationship between artist and sitter who were technically from different sides of the conflict.
