A couple French West Africa internals c. 1944
B_Munro posted an African map in the Map Thread, here's the full res version (you need to open in a new tab):
Hate to rain on your parade here, but muturzikin.com's linguistic maps are notoriously inaccurate. They consistently overrepresent minority languages and overemphasize the divides between dialects of the same language. Look at the maps for a place you're more familiar with if you don't believe me.
EDIT: Now that I look at it, the minority languages in some areas aren't even in the right place. In my home state, they've got overwhelmingly Anglophone places like the Monterey Bay shoreline and the northwestern LA suburbs labeled "español & english", while large stretches of the Central Valley with lots of Spanish-speakers are just labeled "western english".
