This picture shows the Mende devil known as Falwi. I believe it was taken at the Kenema Agricultural Festival (Kenema Cacao Show) which was an annual event each December. The boy on the right is playing the Kellei - a hollowed out log played by drumming with sticks. A man just discernible to the devil's right has a Jeke or shake-shake in his hands. I remember this devil as a secular devil usually seen in celebrations or other fancy gatherings.
