This commemorative stamp set from Christmas Island (Indian Ocean) illustrates key moments connected with the historic 1888 annexation of Christmas Island by Britain. The designs depict the formal annexation ceremony, sailors building a cairn of stones to mark possession, a portrait of Captain William Henry May, and the naval vessel H.M.S. Imperieuse saluting the flag. Issued to commemorate the centenary of annexation, the stamps highlight the island’s colonial maritime history and the role of the Royal Navy in claiming the territory. The detailed illustrations and historical narrative make this a highly attractive thematic set for collectors interested in exploration, naval history, and colonial heritage. Complete sets in fresh condition are particularly desirable for topical collections of islands, maritime events, and British Empire history.
