An adult male instructor sits at a simple wooden lectern, facing a classroom of approximately 15-20 students in Osu, Nigeria. The instructor wears a patterned, multi-colored shirt and a dark, patterned cap. Behind him, a light-colored, textured wall displays four teaching boards: two whiteboards on the left are densely covered with handwritten text, followed by a green chalkboard featuring mathematical equations including derivatives, and a fourth whiteboard on the far right also covered in handwritten notes. A brown, four-bladed ceiling fan is suspended from the ceiling. Students, primarily viewed from behind, occupy rows of seats; their attire includes a grey t-shirt with "NIGHTHOOD" text, a red and yellow striped shirt, and other casual clothing. A dark vertical structural column is visible on the left side of the frame.
