Four Registered envelopes with various KGVI low value definitive combinations, each with a N.T.F. charity label affixed and cancelled LEADENHALL ST. B.O. 31. MR. 50. The labels were available at Post Offices but had no postal validity and were not popular with many P.O. staff. The charity was set up to express Britain’s gratitude to the Commonwealth and the United States for their gift parcels and bulk food supplies since 1940. Delightful group.
