This week’s Mystery Photo, the 100th in a series that began four years ago, most likely was published in the Observer-Reporter or the Waynesburg Republican in the 1970s, but exactly when we do not know.

Nor do we know the identity of the women in the picture found at our Waynesburg office. We’re hoping that our readers can help us identify them and fill us in on what they were doing, and where. The women in the foreground are holding – or passing – some kind of ledger. The knotty-pine background may offer a clue to the location.

If you think you can identify the group or know what they were doing, email Park Burroughs, retired executive editor, at pburroughs@observer-reporter.com, or call and leave a message for him at 724-222-2200, extension 2400.

With a little help from our readers, we should be able to solve this puzzle and publish our findings next Monday.
