Militarism/Imperialism. Another British recruitment poster. England had over the years fallen behind Germany in military strength. England hoped to gain more manpower by recruiting men from its western colony Canada which was still governed by the UK and had the king of England as the head of state. This was a good example of how Britain was able to use its empire.
Based on James Whistler's famous painting of his mother, this poster urges men to enlist with the Irish Canadian Rangers and to fight for the women in their own lives. It appeals to notions of motherhood and family values that were popular at the time, and often attributed to this painting.
