The sheet depicts a full-length portrait of a middle-aged man with a moustache, executed in charcoal after a work by the German-British artist Erich Wolfsfeld. The model is presented at an angle, with clearly drawn facial features: the moustache, the shape of the nose, and the line of the eyes are outlined in detail. His gaze is directed away from the viewer, which gives the portrait psychological expressiveness and inner concentration. The head and neck in a stand-up collar are depicted without a background, emphasising the portrait features. Hatching is used to indicate the volume of the face and soft shadows on the neck and chin. Clothing and other secondary details are treated schematically, allowing the viewer to focus on the model's individual features. The linear manner and style of the drawing indicate the artist's academic approach and his interest in capturing the subject's morphological features. Yulian Zaiats' drawing exemplifies Erich Wolfsveld's traditional portrait techniques – generalised contours, controlled hatching, and an effort to combine realistic accuracy with laconic graphic solutions.
