STB06 An amazing first day cover from 1977 for the RAF Escaping Society with all its commemorative franks which was specially & historically flown nearly 50 years ago through a fantastic military journey of New Britian (see scan) which the Captain of the flight (Capt R.L. Wilkinson) has personally signed the souvenir in mint condition. (other covers of this souvenir are not signed by the Captain) and has Chelsea frank on reverse too exclusive to this cover.
