$90 Killed this U-Boat!

This 1943 poster uses a dramatic image of a Canadian destroyer (right) sinking a German U-Boat (submarine) (left) to raise money for the war effort.

Naval themes and imagery were used throughout the war for fundraising and patriotic purposes, and this poster sends the message that Canadians could directly help destroy U-Boats through their financial contributions. War Savings Stamps were part of the Canadian government's program of fund-raising to help pay the war's enormous costs. Ultimately, some $50 million was raised through the purchase of the 25 cent stamps.
