Identity Cards

This is my father’s wartime ID card found in a box. It was introduced as a wartime measure and abandoned in 1951 when the government found that the cost of maintaining the card far exceeded any cost benefits there might be. ID cards have generally been a failure in this country and have only been tolerated by the public in wartime. The only function of this one that was tolerated was its need to be produced for the issuance of food coupons.

Everything that was printed seemed to be a grey-green in those days; I wonder if this had anything to do with the recycling of paper?
My father was reassigned to work for Sperry Gyroscopes during the war and obviously lived there during the week and returned home at the weekend. I assume from the date stamp that he returned to Wolverton permanently after 9th October 1944
