This Malagasy stamp from the 1960s, valued at 20 Francs, highlights the national duty of reforestation. Issued by the République Malgache, it features a scene of citizens—adults and children—planting trees in a stylized rural landscape. The inscription "Adidy amin'ny Firenena ny Fambolen-kazo" (Tree Planting is a National Duty) emphasizes environmental responsibility. Bilingual text (French and Malagasy) reinforces the unity of purpose and cultural pride. The illustration is a call to civic and ecological engagement during the post-independence nation-building era.
