The Co-Ed

In an age where the majority of college students are women, is the term co-ed even used?  Anyway, I have no idea if this young lady is a college student.  There's  nothing written on the back of the print, but she looks the right age and that's some sort of institutional type architecture in the background.  I'm having a hard time guessing when this photo might have been taken.  The hair and the clothes, I think, could have been found as early as the late twenties to the very early fifties, though my feeling is the thirties.
