This is a vintage, black and white drawing that appears to be a depiction of a hallucination, likely from a psychological or medical context. The drawing is done in a chaotic, scribbled style, with a multitude of swirling lines and shapes that vaguely suggest a human face. The face is framed by a roughly rectangular outline, and within this outline, the features are distorted and fragmented. There are areas that hint at eyes, a nose, and a mouth, but they are all rendered in a highly abstract and unsettling manner. The lines are dense and overlapping, creating a sense of confusion and disorientation. The overall impression is one of mental turmoil and instability. The drawing seems to capture the fragmented and distorted perceptions that might occur during a hallucinatory experience. Below the drawing, there is text in German, likely a caption or description of the image. The text reads: "Fall 26. Abb. 57. „Lufterscheinung.“ Halluzination (Bleistift). 19×33". The drawing is done in a pencil or graphite style, with varying line weights and textures.
