This historical commemorative pair issued by Colombia in 1969 marks the 150th anniversary of the Liberating Campaign of 1819, a decisive movement in the country’s independence history led by Simón Bolívar. The stamps portray dramatic painted battle scenes depicting military encounters and the hardships of revolutionary forces during the campaign. With their classic engraved-style artwork, muted historical tones, and clear anniversary inscription, the set stands out as a meaningful patriotic issue of the late 1960s. These stamps are popular among collectors of Latin American independence themes, military history, and national commemoratives, especially when preserved together as a complete pair.
