1-centime Navigation & Commerce, postmarked on 25 May 1894
In 1892 the French omnibus Navigation and Commerce issue of postage stamps included types specifically intended for use in the island of Anjouan. These were inscribed "SULTANAT / D'ANJOUAN". A series of surcharged values issued in 1912 was available for use in Madagascar and all of the Comoros, and thereafter stamps of Madagascar were used. In 1950 Anjouan used the stamps of the Comoros.
