French Congo

French Congo was established as a French protectorate in 1880. It was essentially the same area as today's Republic of the Congo (Brazzaville). It was merged with Gabon in 1891 and became Middle Congo, though continued to issue its own stamps through 1903.  File:French Congo 2nd ovpt.jpg|1891-92 5c on 20c value; unknown if genuine.
