Issued by Senegal in 1967, this 70-franc stamp commemorates the Pan-African Congress of Prehistory and features an engraved illustration of ancient Bandiala ceramic pottery, highlighting West Africa’s archaeological heritage. The bold blue and red intaglio-style design gives strong visual contrast, typical of mid-1960s African cultural issues. Its scholarly theme appeals to collectors of archaeology, anthropology, and African history. A distinctive subject that stands apart from standard definitives, making it attractive for thematic and congress-related collections. Ideal for Africa, prehistory, or traditional crafts exhibits.
