Last week, Africa Is a Country, a blog that documents and skewers Western misconceptions of Africa, ran a fascinating story about book design. It posted a collage of 36 covers of books that were either set in Africa or written by African writers. The texts of the books were as diverse as the geography they covered: Nigeria, Zimbabwe, South Africa, Botswana, Zambia, Mozambique. They were written in wildly divergent styles, by writers that included several Nobel Prize winners. Yet all of books’ covers featured an acacia tree, an orange sunset over the veld, or both.
