Distressed face mural spotted on London wall

The image captures a monochrome mural depicting a man's face in a state of distress or pain, possibly screaming, with exaggerated facial features. The artwork appears to be sprayed or painted on a wall, which shows signs of cracks and weathering. A small square drain or vent is visible on the wall near the lower portion of the mural. It is not possible to identify the location in London, United Kingdom, from the image alone.
