Gilberdyke school old photo of Mrs Sellers' class

Following on from my previous post about Staddlethorpe station here is another piece of  Gilberdyke  history. In the same file as before I have found a picture of a Gilberdyke school class. I do not know the date - although the teacher again is Mrs Sellers.

I would love to know who the children are and when the picture was taken.
