Argentina "Rivadavia" Portrait, Imperforate

Argentina · 1864 · 5c

This classic stamp features a portrait of Bernardino Rivadavia, the first president of Argentina. The design is notable for its simplicity and the use of lithography, a common printing method for early stamps. As one of Argentina's first definitive series, it was used for standard postal rates.

Issued during a period of national consolidation, the Rivadavia series helped establish a unified postal system across the Argentine Republic following decades of civil strife.
