Here's a postcard that matches this doll. It shows how the people living in Burkina Faso are dressed in their traditional costume.
Text on the back of the postcard: 'Haute-Volta. Au marché, en saison sèche. Aimable sourire d'une petite vendeuse d'au'. Stamp removed, not dated but must be from before 1984. (Upper Volta was renamed Burkina Faso in 1984). Sent from Ouagadougou.
