Clara Apt postcard

This photograph was found among my grandmother's old family photos. It is a postcard photo sent to Miss Clara Apt in Butler, IN. We do not know who is in the picture.

The message on the back says:

"August 6, 1900

Here is your postal. I thought I would send it right away before I forgot it. How do you feel after a day at Alvordton?

Wilma" (possibly - hard to make out the name)


Who are these women? I do not know where the photo was taken, or from where the postcard was mailed, but I do know it was sent to Clara Apt in Butler, IN.
