The island is known by
philatelists for having issued its own
postage stamps between 1903 and 1910. The first issue depicted a profile of the young
Alfonso XIII of Spain, and consisted of 18 values, from ¼
centimos to 10
pesetas. In 1905, the values of 1c to 10 ptas were reprinted, although with the same date. The 1906 issue was made by means of ratings stamped on the previous series. The 1907 series consisted of 16 values between 1c and 10 ptas, updated to a profile of an older Alfonso. Several of these values were
surcharged between 1908 and 1910. A total of 72 issues are identified in the
Yvert catalogue. Subsequently, the island used the stamps of
Spanish Guinea. == Literature ==
