Books such as this were isued by the British government to combat petrol shortages during the 1973 Oil Crisis. The Organisation of Petroleum Producing Countries (OPEC) imposed an oil embargo on Western countries which had supported Israel during the Arab-Israeli Yom Kippur war. Oil prices quadrupled, and supplies were restricted, leading to the imposition of petrol rationing in Britain and other parts of Western Europe dependent on oil imports from Arab states. Ration books were made out for particular motor cars on the basis of engine size and horse-power. This particular book was isued for a Citroen car of engine size not exceeding 1100 cc (1-9 hp). It contains coupons to the value of 24 x 'N' units and 12 x 'L' units, all for a six month period.
