The Cape Guardafui Lighthouse - 7 1/2 centesimo

This brown 5-centesimi issue from the same 1932 pictorial definitive series honors a crucial maritime landmark at the geographical tip of the Horn of Africa. The horizontal engraving illustrates the iconic Francesco Crispi Lighthouse, built by Italian maritime engineers atop the rocky headland of Cape Guardafui (Capo Guardafui), where the Gulf of Aden meets the Indian Ocean. Guarding one of the world's most vital and historically hazardous shipping lanes, the lighthouse is depicted sweeping its beacon across the sea. The stamp features a lower-right Arabic value tablet ("بيسات ٥"), seamlessly connecting regional infrastructure and safety along international trade routes with the territorial postal system.
