Gas rationing booklet. This is the inside of the front cover and the first page of the new "A" gasoline coupon book, which motorists in the East Coast rationed area will need to obtain their basic rations of gasoline when the coupon plan goes into effect in July. Instructions appearing inside the front cover warn holders against tearing out the coupons and presenting them loose at a service station. The six coupons on the first page are marked "A-1," which means they may be used at any time during the first two months after the plan goes into effect. Coupons on the following pages are numbered "A-2," "A-3," etc., and will be good during the respective two-month periods. The book rations gasoline for the period of one year
