Have obtained one copy of this very popular cover.
First day cover for "End of War" miniature sheet from Royal Mail. The Stamps and cancels both form the V for victory sign. The St Paul's stamps has been actually been struck twice with the cancel. A rare and valuable mistake.
The painting on the cover is exclusive to BPPO and shows how the Britain's "secret little post office" might have looked soon after "It's Over"
Behind every character is a story told on the cover insert. The cover also includes a WW2 ration book and ID card issued from Bletchley Park.
