Issued by Spain in 1973, this 2 pesetas stamp commemorates the 50th anniversary of the Consejo Superior Geográfico (1923–1973). The design features a richly detailed 14th-century nautical chart (Carta Náutica, Siglo XIV), showcasing early cartographic depictions of the Iberian Peninsula and surrounding seas. The intricate rhumb lines, compass rose, and maritime illustrations reflect the navigational artistry of the medieval age. A fine piece for collectors interested in historical cartography and Spanish geographic heritage.
