Ein Mann auf einem Stuhl sitzend in Unterhaltung mit einem Jungen 

This drawing by Johann Ludwig Aberli depicts a man and a young boy seated in conversation. The man is seated on a stool, while the boy sits on the ground, leaning against his leg. Aberli, a Swiss painter, is known for his detailed and realistic depictions of everyday life. The loose, sketched lines and muted colors of this work give it a sense of spontaneity and intimacy, capturing a fleeting moment in time. The drawing, likely a preliminary study, offers a glimpse into Aberli's artistic process and his interest in depicting everyday interactions.
