All hail the might Zanzibar Clove! Zanzibar is a semi-autonomous archipelago off the coast of Tanzania and was once the world's leading producer of cloves. The economy is largely clove-based and now that the market has shifted, the islands are suffering. Uhuru, emblazoned at the top of this stamp, is the Swahili word for Freedom. Around the time this stamp was printed, the archipelago went from being a British protectorate to an independent sultanate, then joined with Tanganyika to form Tanzania. You're sure to command respect in this unusual t-shirt.
