A striking early engraved issue from Zanzibar, featuring a dignified portrait of the Sultan framed within an ornate oval design typical of late-19th/early-20th century colonial philately. The bold “10 Cents” denomination and “ZANZIBAR” inscription emphasize its postal and historical significance. Fine line engraving and deep black printing give this stamp strong visual depth, highly appealing to collectors of African states and classic monarchy issues. Red postal overprints/cancellations add authentic postal character. A desirable piece for Indian Ocean, British influence, and classic portrait collections.
