This 250 Franc airmail stamp was issued by the Islamic Republic of Mauritania in 1965 to commemorate the centenary of the International Telecommunication Union (UIT), founded in 1865. The design, by Durrens, features a historic telegraph instrument on the left and a communications satellite on the right, symbolizing a century of progress in global communications. At the center is the ITU emblem with a lightning bolt across a globe, representing worldwide connectivity. Issued during a period of rapid technological change, this high-denomination stamp highlights Mauritania’s participation in international communication networks.
