This photo, from Gladys Dutton's collection, is marked 'Jonas, French Teacher'. We do not know which of these two women is Jonas. They are both wearing panama hats and either a cardigan or a knitted dress.
It is possible that the beach may have been at Friog where the school had a beach hut. DWS girls went swimming there for many years.
In the background you can just see a girl in a swimming costume.
