This 1967 pair from the Republic of Congo highlights two national initiatives promoting progress and education. The 45 Franc “Campagne pour la Canne à Sucre” depicts workers harvesting sugarcane before a factory backdrop, symbolizing agricultural productivity and industrial growth. The 25 Franc “Campagne d’Alphabétisation” shows a teacher and student at a chalkboard, emphasizing literacy and empowerment through education. Designed by Guillaume after J. Balou and engraved by Delrieu, these stamps exemplify the post-independence optimism and social reform efforts of the 1960s Congo.
