Ethnographic drawings of two objects from the collection of the National Museum of Ethnology. The largest, on the right, depicts the sculpture "Ninte Kamatchol" (Inv. Nr.: AO.335), used by the Nalu (Guinea Bissau) in male initiation rituals. It also plays an important role in agrarian rites as in funerary rites of dignitaries. The smallest drawing, on the left, depicts the upper section of a "Nimba" (Inv. Nr.: AD.084), a mask used by the Nalu (Cacine, Campeane, Guinea-Bissau) in festivals related to the rice harvest and funerary ceremonies.
