210 x 161 mm. Showing two Europeans and a number of white-coated African assistants standing in a large corrugated-iron store or warehouse. Piled around them are boxes, sacks and barrels of miscellaneous produce, with bottles and cans stored on shelves around the walls. The identification of the location as Opobo is tentative and relies on the fact that the name is written on one of the supporting girders of the building. Opobo, situated 40 miles east-south-east of Port Harcourt at the mouth of the Imo River (also called Opobo River), is also known as Egwanga. The British trading station lay four miles south-south-west across the Opobo River from the original settlement.
