Coupon Value -- Film Description:
"With the plight of European peoples during World War II as an example, Canadian housewives were urged to make use of food as a weapon of freedom for the Allies. Army requirements had foremost consideration, and Canada shipped large quantities of foodstuffs to Britain. Home consumption therefore had to be cut by twenty percent, and that meant the introduction of meat rationing. A coupon value chart was distributed to housewives to teach them coupon wisdom."
