The photograph titled “Masked man at a ball, N.Y.C.” is a work by Diane Arbus from the year 1967. In this black and white image, the subject is a man wearing a formal tuxedo with a bow tie, his face partially obscured by a thin, semi-transparent mask that covers his eyes and the bridge of his nose. The mask appears to be made of a lightweight fabric, allowing his facial features to be visible beneath it. He looks directly into the camera, his expression carrying a mix of seriousness and perhaps a hint of bemusement. The man’s hair is neatly combed and his demeanor seems calm. The background is dark and indistinct, emphasizing the subject’s face and attire.
