Sierra Leone was one of seven African nations that issued Gandhi stamps in 1998.  The others included Gambia, Ghana and Liberia in West Africa; Tanzania, Uganda and Zambia in East Africa.  The set included two stamps, a lower value of 600Le (which was printed in a souvenir sheet as a block of four) and a higher 2000Le value in a smaller souvenir sheet.  The design follows the same theme as the 1998 Gandhi issues from Dominica, Liberia, St. Vincent, Tanzania, Uganda and Zambia.
