This 15 milliemes airmail stamp from Egypt, issued on February 1, 1958, celebrates the historic formation of the United Arab Republic (UAR) — the short-lived political union between Egypt and Syria. The design depicts stylized maps of both nations joined by an arch inscribed in Arabic, symbolizing unity under one republic, with an aircraft flying above and the rising sun in the background signifying a new era. The issue marks a key moment in Arab nationalism, making it an essential piece for collectors of Middle Eastern or political history themes.
