This is a WW2 banknote. 1944, September16th, saw the end of the conference in Quebec attended by Churchill. Also the date when the Russians occupied Sofia in Bulgaria. The banknote is AF in grade. It is clearly soiled, circulated and well used. However, it is a WW2 note and to see any such  note being offered for under £100 is rare indeed. So, this is a great offer and an opportunity to own a WW2 note. Great value and free GB postage.
