Photo Number Ninety-Nine

This is a photo from South Dakota/ Illinois.  This is Edna  Flisner or Flisnes her photo was taken at Wilkes or Wilker 3810 State Street Chicago.  The dark folders are very difficult to read. I would venture to guess that this was taken around 1900. ( Changing my guess to 1910 )  She has on a single strand of pearls.
Thanks for stopping by, do come again:)
Update ***
From Norkio:Well, Ancestry says there is an Edna Flessner born in 1888 in Illinois who by 1910 was in South Dakota. What are the chances? Ms Flessner was 22 in 1910 and living at a school district (??) so perhaps she was a teacher?
