Bulletin du Comité d'études historiques et scientifiques de l'Afrique occidentale française
This is a 1918 bulletin published in Paris by the Comité d'études historiques et scientifiques de l'Afrique occidentale française, a French colonial learned society, for scholars of French West Africa. Its plates are black-and-white photographs and line drawings of fossils and worked stones, with scale numbers, compass diagrams and geological sketches. A designer might take the rough, textured shapes of weathered stone, the radiating ribbed bivalve forms, and the precise technical lettering and diagram layouts.
