The brand focuses on the groundbreaking ethnographic missions conducted in sub-Saharan Africa from 1928 to 1939, marking a pivotal moment in the development of French ethnology. Spearheaded by early students of the Paris Institute of Ethnology, these missions aimed to collect cultural data and objects, providing essential field experience for budding ethnologists. The website serves as a comprehensive resource, showcasing a blend of explanatory texts and archival documents that detail the expeditions' processes, outcomes, methodologies, and the various individuals and organizations involved.

The platform offers a rich array of ethnographic materials, including musical ethnology, ethnobotany, ethnozoology, and linguistic surveys, alongside collections of Ethiopian paintings and manuscripts. It also hosts photographs and audiovisual documentation of the missions. Partnering with institutions like the Éric-de-Dampierre Library, the National Library of France, and the Quai Branly Museum, the site aims to enrich public understanding of these historical missions, providing access to a carefully curated selection of digitized documents that illustrate the methods and achievements of the time.
