Answer: The Vatican issued its first aerogramme or air letter sheet on January 10, 1950. 3 aerogrammes were issued in 1950; 1 each year 1951-1954; 1 in 1958; 1 in 1962. At least 1 aerogramme has been issued each year since 1975. 2 aerogrammes were issued in 1975 and1979. An aerogramme or air letter sheet is a thin lightweight piece of foldable and gummed paper for writing a letter for transit via airmail, in which the letter and envelope are one and the same. Most postal administrations forbid enclosures in these light letters, which are usually sent abroad at a preferential rate. Source: Wikipedia.
