The flag is made of wool bunting, the applied lettering is hand sewn while the seams of the flag are machine sewn. It has a linen hoist containing a rope.

The title of 'Governor of Benin River' was given to Nana Olomu by the British in 1884. He exerted immense political power through a network of armed traders in palm oil working along the upper reaches of the river and he built a town in the mangrove swamps defended by flintlock guns and brass cannon. Partly through the machinations of a rival chief - Dogho, relations deteriorated with the acting Consul-General Ralph Moor In 1894. Following an attack on HMS Alecto's cutter which was inspecting Nana's fortifications, a British naval expedition captured Nanna's town of Ebrohimi. He fled to Lagos Colony, but was tried and exiled to the Gold Coast from 1894-1906. After his return to Nigeria he lived at the town of Koko.
