A striking purple and black 12 centavos revenue stamp issued during El Salvador’s revolutionary/insurrectionary period, inscribed “Centenario de la Insurrección.” The design features a bold five-pointed star enclosing a monument scene, symbolizing national struggle and independence. Originally produced for fiscal/revenue purposes, but widely collected alongside postal back-of-the-book issues. The intricate line engraving, star medallions, and strong typography make it visually dramatic. Popular among collectors of Central America, revolution themes, and revenues/semi-postals. A scarce and historically significant piece representing El Salvador’s political heritage.
