Postcard. No maker's name.
Johns' 1911 directory gives the following information about the school:
Erected 1866, enlarged 1897 for 520 boys, 412 girls and 353 infants. Boys' master Mr. L. Thomas, girls' mistress Miss A. A. Barber, infants' mistress Miss S. M. Williams.
The boys' master in 1907 was Mr. P. G. Gale. My guess is this is the bearded man left of picture.
