This is a photograph of a class of schoolchildren taken at Sunniside in County Durham. I am trying to make out what is written on the board held by the girl in the centre of the front row. It starts with the words "Sunniside", then there is a date which seems to be 8th December, 1921. Has anyone the ability and the eyesight to make out exactly what is on the board? To get a larger view of it just click into the picture.

On the right of the girl holding the board (our left) is my mother who was born on 20 February, 1909. If I am correct about the date on the board, then she would be 12.
