The two world wars in terms of food security of Great Britain and its allies took place according to a similar scenario. As the British were dependent on outside supplies, had to rely on the United States and Canada. Those, helping the allies, also urged their citizens to be a bit more modest.
Well, the Germans actively obstructed supplies. The philistines were urged that every piece of bread is equally important as a bullet or a grenade, that home canning is a strategic issue, food speculators are enemies of the state, etc. Lets's see.
American posters of World War I and II, respectively: «Save a loaf a week — help win the war» and «Food is a weapon, do not waste it! Buy wisely, cook carefully, eat it all»
On the left, an American proposal to switch to fish: «Save the products of the land — eat more fish, they feed themselves." The British poster on the right urges not to waste food, rightly remarking that «a pot-luck with Churchill today is better than a humble Hitler pie tomorrow." The poster word plays «luck» and «humiliation»
Two American World War II posters calling to conservate everything is possible. Two meanings of the word Can are played again — «to have the opportunity» and «tin can»
The Canadian World War I poster on the left reminds of the persecution of food speculators and informs that patriotic Canadians do not hoard food. American poster on the right proposes not to pay speculators more than the legal price and use ration stamps to destroy the black market
The American poster on the left calls for saving food, which is the fuel too: «Know the capacity of your bunker!» The housewife on the poster on the right promises not to buy food at a speculative price and not to buy goods that are not liable to rationing, while using the ration stamps
