A Girl sitting across two deckchairs

A picture of a girl sitting across two deckchairs with a somewhat pensive look on her face. Beneath the chair she is sitting on are a pair of shoes and a large collection of towels, bags and other beach stuff is piled up next to it.

I wonder what she was thinking as she sat cross legged on that chair? Possibly she was watching friends in the sea and thinking of joining them.

I don't know the accurate date this picture was taken, but it was probably in the late 1950s.
