Tanganyika G.E.A. Occupation Overprint

Tanganyika · 1916 · 3 Heller

This stamp is an overprint on a German East Africa issue, specifically the 3 Heller value from the 1905 Hohenzollern Yacht series. The overprint reads "G.E.A." in sans-serif capitals, signifying the British occupation of the territory during World War I. The original design features the imperial yacht SMY Hohenzollern within an ornate frame.

Issued during the East African Campaign of World War I, these overprints marked the transition of postal authority from German to British military administration in captured territories of German East Africa (Deutsch-Ostafrika).
