This striking airmail issue from the Islamic Republic of Mauritania features a symbolic design promoting the global fight against cancer. The artwork shows a powerful fist emitting lightning bolts directed at a red crab, the ancient symbol of cancer, emphasizing strength and determination in overcoming the disease. The French inscription “Lutte Contre le Cancer” (“Fight Against Cancer”) highlights its public health message. Issued during the 1970s, this 100 Franc stamp represents both Mauritania’s participation in international health awareness campaigns and its contribution to thematic philately. A highly collectible piece, it appeals to collectors of medical, humanitarian, and symbolic stamp themes.
