Who is the mystery man in this portrait?
A gallery has corrected the title of a portrait by British artist Tom McGuinness after the artist's daughter identified the subject as an unknown man, not her grandfather as originally thought. The drawing, initially labeled "Cathy's Dad," has been renamed "Portrait of an Unknown Man" and is included in the exhibition "Tom McGuinness: Out of the Darkness," which runs through the rest of the year and features oil paintings, sketches, lithographs, and family portraits.
