Portraits of Mother, by Albrecht Durer, 1510-1514, housed at the Durer Art Gallery in Berlin. [Photo/Artron.net]

The charcoal-made artwork was created two months before Durer's mother passed away. The lady in the portrait has a weather-worn face, and looks kind and sincere. The art piece, which shows his respect and love to his mother, is the only portrait of Durer's mother.
