1938-1952 Kenya, Uganda, and Tanganyika 15c Mount Kilimanjaro Postage Stamp (King George VI)

This is a used British colonial postage stamp issued for the joint postal administration of Kenya, Uganda, and Tanganyika. The stamp features a bicolored design: a central vignette of Mount Kilimanjaro in a dark slate-green or blackish-green hue, surrounded by a carmine-red or reddish-brown ornate frame. In the upper right corner is a circular portrait of King George VI, indicating a manufacturing date between 1938 and 1952. The stamp has a face value of 15 cents, and it bears the horizontal inscription 'UGANDA' at the top and 'TANGANYIKA' at the bottom, with 'KENYA' written vertically on the right side. The printing is a fine-line intaglio or recess print, showcasing high-quality craftsmanship typical of the De La Rue or Bradbury Wilkinson printing firms of that era. Physically, the stamp exhibits standard perforations around all four edges, though some teeth appear slightly uneven. A visible black circular date stamp (CDS) or handstamp cancellation is present, crossing over the King's portrait and the mountain scene, which confirms its post-usage status. There is minor evidence of handling, including slight surface wear and possible light aging of the paper stock, but the colors remain relatively vibrant for its age. The centering is slightly off toward the top-right corner. This series is well-documented in philatelic catalogs and represents a period of unified colonial administration in East Africa.
