Niger
1972 On November 23, 1972, the Republic of Niger issued a set of air mail stamps in honor of Jean de la Fontaine, including FC, LM, and "The Singe et le Leopard." The official post office turned these new stamps into a set of envelopes reflecting the style of the newly issued stamps. I have also come by a set of proof specimens of the three stamps and a set of two imperforates.
