Portrait of Mr Koch 

Johann Heinrich Hasselhorst's "Portrait of Mr Koch" is a pencil drawing that captures a man in profile, likely a portrait of a private individual. The artist, born in 1825, utilizes a simple yet refined approach to depict the sitter's features. Hasselhorst's signature and the sitter's name are clearly visible in the lower right corner of the drawing, adding a personal touch to this realistic depiction. The drawing, currently housed at the Städel Museum, offers a glimpse into the artist's skill in portraying human likeness with a delicate touch.
