Portrait of three ladies - 1920s

This is a portrait of three young ladies sitting together on a seat, with the girl in the middle having her arms around the shoulders of the two on the outside. It looks as if they have stopped and posed for their companion who has the camera and is taking the picture.

Although the quality of the picture is reasonable considering the age, it was scanned from a black & white print, and is not as sharp as it would be if it were scanned from the negative.

I don't know the date this was taken, but I suspect that it was in the 1920s based on the clothes the girls are wearing.
