Netherton schoolmaster

This photo is just labelled "Mr Boll" - presumably he's the man in the middle or one of the two just behind. It was taken in about 1912, outside the Infants School at Netherton which was opposite Third Street. Mr Boll became Headmaster of Nedderton Village School. The group pose and button holes some of the boys are wearing suggest a special event but I don't know what it was. If anyone knows more about this photo please send me a message to let me know and include the details.
