This striking issue comes from the Morocco Agencies postal service under British administration. Originally a ½d definitive of King Edward VIII in red-brown, it was overprinted in black with "MOROCCO AGENCIES" and surcharged to 15 centimos for local use in Spanish currency. Issued during the brief reign of Edward VIII (1936), these stamps are prized as his abdication led to limited postal issues. The portrait depicts Edward VIII in profile, with the crown above. A scarce colonial overprint, this stamp represents both imperial postal history and the short-lived monarchy. Collectors seek it for its historical significance and rarity in well-preserved condition.
