A striking 50 Franc airmail issue from the Republic of Chad, released in 1964 to promote the Europafrique concept of strengthened cooperation between Europe and Africa. The design features stylized golden orbit lines encircling the two continents, symbolizing communication, development, and air links. Printed in bold green, white, and deep brown tones, the stamp captures the optimism of mid-20th-century international partnership. A desirable thematic item for collectors of Africa, airmail issues, and geopolitical / development themes.
