1972 Two Dahomey FDC envelopes featuring FS (35F) and "Le Chat, la Belette et le petit Lapin" (40F). August 28, 1972. Cotonou. République du Dahomey. $9.70 from Gilles Descary, St.-Jean-sur-Richelieu, Canada, through eBay, May, '04.
Each envelope works well with the design of its stamp, selecting and transforming slightly. Each gives the title of its fable and the name and dates of La Fontaine.
