It shows two women - one appears to be wearing a white school gymslip, but she seems rather too old to be comfortable in such clothes, presumably an older teenager.
The woman with her is wearing a surprisingly mannish dark suit, and has her hair styled to cover one eye.
Perhaps the older woman is a relative? They seem to be standing a little too close to be pupil and teacher.
It looks rather as if it has been taken in a park or perhaps a very large garden.
