A history of African art (not graphic design contrary to the title) is:

Interesting websites with artists are:

• http://africandigitalart.com/tag/william-santiago/
• http://africandigitalart.com/category/artist/
• Indaba has a directory of African designers: http://www.designindaba.com
• See also http://www.designindaba.com for directory of African designers.
• Middle East and Africa: https://design.tutsplus.com/tutorials/100-artworks-from-the-top-20-designers-in-the-middle-east-and-africa–psd-5036

A Google search for African typefaces tend to be rather kitsch zebras and unusable. Not the typefaces more commonly used in Africa – these are the common Adobe and Microsoft ones. But African designers have used these with colours in slightly different ways that I have yet to properly analyse.

There is no Wikipedia on African Graphic Design!!!
