Photographer Sergio Pessolano took some amazing photos of the Mursi people in Ethiopia:
The Mursi (or Murzu) are a Sub-Saharan African nomadic cattle herder tribe located in the Omo valley in southwestern Ethiopia close to the Sudanese border.
The estimated population of the Mursi is around 3900. Surrounded by mountains and three rivers, the home of the Mursi is one of the most isolated region of the country. [...]
The Mursi women are famous of wearing plates in their lower lips. The reason of this "ornament" is for avoiding to be
catchedcaught as slaves.
These lip discs are made of clay. Girls are pierced in the age of 15 or 16. They remove the plate when eating.
