An artist of this name exhibited in Penzance in June 1996 at The Bakehouse Gallery in Penzance.
A correspondent (2016) who knew Mary Ball when she was living in Greenwich, London, in the 1970s, has provided further information on this artist. She moved to Cornwall in 1994, making her home initially in Newlyn and subsequently settling in Penzance, where she died. The Bakehouse Gallery exhibition catalogue is entitled 'Mary Ball - Recent Textiles' and states: 'This work is to do with time and chance and change. It is in process of becoming. It takes ideas from landscape.'
The correspondent describes Mary Ball as a pioneer in her field, who often felt alone and an outsider.
