Glass plate negative of a three-quarter length portrait of Sarah [Sally] Bonetta Forbes (1843-80) seated, facing the camera front on. She poses with her hands held together in her lap. She wears a small hair covering, dark colour dress with lace collar and sleeves and a bracelet. On the left of the photograph is a table covered in a textile. A bowl holding a textile is placed on the table.

The glass plate negative has been photographed showing the coated side and therefore the image appears laterally reversed. Prints from this negative exist in the Collection (e.g. RCINs 2800762 and 2906613)
