Door Knocker

Alfred Walbeck

National Gallery of Art

This is a drawing of a door knocker. The image showcases a detailed illustration of a vintage door knocker in the center, presented in a realistic style with visible shades and highlights that give it a three-dimensional appearance. On either side of the main illustration are technical sketches in pencil that outline the knocker from different angles, providing side and top views and specifying the design's dimensions. The central knocker features a traditional design with ornate detailing at the top, a square central block, and a handle-like piece that curves down. The muted tones of brown and hints of gold denote its metallic nature. The composition implies a study or design plan for a piece of hardware, with precise dimensions and annotations included in the sketch.
