"The man in the polka-dotted robe is a lecturer in mathematics at the University of Ibadan, in Nigeria. His also, I believe, a chief." J.D-B. in a letter to R.S. D-B from Northfield, Minn., Dec. 24, 1964. I think this was a photo John sent to his father in his 1964 Christmas letter, which he got back after Dick's death. I'm not sure of the writing, though.
