Shortages of essential war materials such as rubber, gasoline, and sugar were initially anticipated, but soon rationing grew to include food as well as fuel and sugar. War ration book no. 3, valid September 1943, included 8 pages of stamps, four for meat rationing, and four for a clothing rationing program never put into effect. Some clothing stamps were eventually validated for shoe rationing.
