These are vintage 1964 panafrican flag pin, in excellent shape. Some are slightly rusted on the back; however, the condition is consistent with age.
About: The Pan-African flag was designed to represent people of the African Diaspora by the Universal Negro Improvement Association in 1914. The flag was designated the official colors of Black people by the UNIA at its convention in New York City in 1920. Their constitution explains the color symbolism: "red representing the noble blood that unites all people of African ancestry, the colour black for the people, green for the rich land of Africa."
