This site has lots of photos and descriptions of rationing books, tokens, and coupons used in WWII. Aren't those little colored tokens cute!
During the Second World War, you couldn't just walk into a shop and buy as much sugar or butter or meat as you wanted, nor could you fill up your car with gasoline whenever you liked. All these things were rationed, which meant you were only allowed to buy a small amount (even if you could afford more). The government introduced rationing because certain things were in short supply during the war, and rationing was the only way to make sure everyone got their fair share. War ration books and tokens were issued to each American family, dictating how much gasoline, tires, sugar, meat, silk, shoes, nylon and other items any one person could buy.World War II Rationing (Thanks, Sam!)
