These cycling schoolgirls, snapped mid-conversation at Glasgow's old St Enoch Station, were, we think, heading home from their classes at one of Glasgow's private schools. They were, in the words of Muriel Spark's Miss Jean Brodie, the 'creme de la creme' of Glasgow girlhood.
With their straw hats, smart blazers, lisle stockings, briefcases and satchels they positively exude class.
The girl in the long duster coat is obviously keeping one eye on the station departure board, to make sure they don't miss their train.
Their bikes, complete with brown paper labels, would no doubt have been loaded into the guard's van for collection at their destination, from where they could cycle the last miles home.
