This unused card was issued by the National Museum of African Art, at the Smithsonian Institution in Washington, D.C., in 1983.  It shows “an attentive audience (watching) two Maasai elders playing mbao”.  We lived exactly there, in the Masai region in Kenya, for quite awhile and never saw anyone playing mbao.  Just the wrong places at the wrong times, maybe.  Grade: 1
