The most significant visual clue is the man's attire. He is wearing a red cap, known as 'Okpu Agu' or 'red chief's cap', and a white tunic, which are traditional for men of the Igbo ethnic group in Nigeria.

The Igbo people are predominantly from Southeastern Nigeria. Enugu is a major city in this region and the historical capital of the former Eastern Region, making it a highly probable location for this photo to be taken.

The image is a studio portrait, so a precise location is impossible to determine; this city is a strong candidate based on cultural context. While the man's clothing is distinctly Igbo from Southeastern Nigeria, Lagos is the commercial capital and largest city in Nigeria.

It is a melting pot of all Nigerian ethnic groups, with a very large Igbo population. Given the high concentration of people and businesses, including countless photo studios, it is very plausible that this portrait was taken in Lagos.

The man's red cap and white tunic are characteristic of the Igbo people. Onitsha is a major commercial city and metropolitan area within the Igbo heartland in Anambra State, Southeastern Nigeria.

It is another highly likely location where this studio photograph could have been taken, given the strong cultural indicators.
