Gretta Jones, Jess Sanders, May Hookinson

The names in the title are listed on the back of the photo. The name "Hookinson" could possibly be Hoskinson or (much less likely) Hoakinson or Honkinson. The third letter looks most like the writer's other "o"s. If any of these names is of possible importance to you, please email for a scan of the writing!
No locations or photographers are identified. This is the only information I have specifically about this photo.
I purchased this in a huge lot of photos from Ebay. They have no traceable history as the seller got them from someone who checks the dumpsters behind estate sales around several states in the midwest! I can only list what is on the individual photos themselves as they all came from different places. That's why I'm posting as many photos as I can, so any more of their history isn't lost. I would be interested to know if they help any family researchers though.
People in photo include: Gretta Jones, Jess Sanders, and May Hookinson
