WW1 National Savings Card & Owners Photograph

National War Savings Card along with photo of owner and colleagues who appear to be Munitions Workers.There were several different types of national saving books designed to encourage the civilian population to fund the war. This book is interesting as the back cover states 'Postage Stamps only must be used'. This is perhaps the only instance of British postage stamps being officially used for a purpose other than 'Postage' or 'Revenue'. The scheme operated between 1916 & 1918. This was replaced by the issue of National War Issue savings stamps late in 1918. Interestingly the last stamp being an actual National War Savings one.
