A middle-aged male teacher in a classic tailcoat, standing in front of a blackboard, with a chalk in the hand that has just struck a tidy and deliberate mark, wearing a pair of wire-rimmed glasses and a friendly expression, with a hint of a smile, looking directly at the viewer with a sense of pride and authority, set against a warm and inviting background of wooden paneling and a hint of books on a nearby shelf.
