Second world war Ration Cards.

In WW11 every civilian had to carry a identity card at all times as proof of identity and address. These had to be produced on demand to the police, members of the Armed Forces on duty and national registration officers. Each card had a personal number of six or seven digits Early in 1943 registration and rationing was combined and, in May of that year, the opportunity was taken to issue a fresh set of identity cards at the same time as the new ration books. Civilian members of the population over 16 received a blue card to replace the previous buff card and under 16 year olds retained their existing buff card. A new type of buff card, which expired on the holder's sixteenth birthday, was issued to children under 16 on those occasions when a fresh card was necessary; on registration at birth; on registration upon entering the country; to replace a lost or damaged card; or on change of name. It was obligatory to carry them everywhere.
