No information about Irene Horsley other than her name. In this getup she looks like she should be playing a bit part in the Music Man. In fact, I'm not sure there wasn't a character in the movie that didn't wear this exact outfit.
I do wonder how old Irene was when this shot was taken. How long did girls wear these huge bows? To say the least, I'm glad it went out of fashion. I've seen some shots of girls far too old to be wearing huge bows in their hair.
It is possible Irene came from Nebraska because this shot was purchased at the same estate sale as the previous two images.
UPDATE: Thank you, Bulldog.
Irene Horsley wife of Claude A. Perry. Born November 29, 1896, died April 9, 1977. (http://nebraskagravestones.org/view.php?id=133923)
