British Military Payment Certificates - Special Vouchers, One Pound. For use in British Service Canteens and organizations. Issued in 1956 (printed in 1948) this is the highest denomination of notes for use by forces posted overseas during the Suez crisis. 

We have a group of nice, premium quality notes with a technical grade of very Choice AU due to barely perceptible handling or a very light fold. Priced very favorably.
