The image shows a male figure in a torso view, standing sideways facing a chalkboard with his face in profile. The person's facial features are abstractly drawn with strong lines accentuating the brow and cheeks, and he has thick, slick-back hair. The figure is wearing a suit jacket with a front pocket and cuff-links. He is holding a piece of chalk in his right hand, extended towards the blackboard. The blackboard is filled with text written in chalk. Beside the main figure, there is another individual shown from the back with a focus on the head, which has short, slicked-back hair, seated and looking at the professor figure. The background is plain with minimal detailing, emphasizing the figures and the chalkboard.
