Door Knocker

Robert Frederick Blum's sketch depicts a grotesque face emerging from ornamental metalwork—likely a study for a decorative door knocker. The ink drawing, rendered with quick, confident lines, captures exaggerated facial features and flowing hair rendered through parallel hatching. Blum, an accomplished illustrator and painter, was active during the golden age of newspaper illustration. His work in publications like *Life* and *Puck* helped establish the visual conventions of American comics: sequential narrative, expressive linework, and character variation. Though this sketch predates the formal comic strip, it demonstrates the foundational drawing skills—anatomical distortion, rapid execution, compositional clarity—that would define the medium's pioneers.
