Portrait adds a dusting of mystery to exhibition in Bishop Auckland

A mystery portrait has prompted a public appeal in County Durham as a major new exhibition celebrating miner-artist Tom McGuinness opens at Bishop Auckland’s Mining Art Gallery. Visitors are being asked to help identify an unknown man depicted in a 1963 charcoal drawing, *Portrait of an Unknown Man*, now on display as part of *Tom McGuinness: Out of the Darkness*, which marks the centenary of the artist’s birth and runs throughout 2026. McGuinness, born in Witton Park, worked in the mines for nearly four decades, and his art captures the physical and emotional realities of mining life. The portrait was initially thought to depict the artist’s father-in-law, but his daughter Corinne Aspel has challenged that assumption, noting clear differences in facial features.
