caption: The image shows four black and white drawings of four old men with long beards on a piece of paper. Each man has a distinct facial expression, ranging from a serious expression to a more inquisitive look. His eyes are wide and his mouth is slightly open, as if he is about to speak. His hair is long and wavy, and his clothing is simple and plain. The background of the paper is plain and unadorned, allowing the drawings to stand out.
