It’s amazing how many rare African art books can be found online these days; I just stumbled upon Les nègres by Maurice Delafosse from 1927. You can download the book here or directly go to plates here – including incredible field-photo’s from Delafosse himself, Petit, Muraz and the Citroën Expedition. Reminds me that I still have to make an appointment for a dental check-up :)
