This remarkably expansive photo shows a studio scene with three nude models, a clothed attendant amond the models, and three additional clothed men off to the left side. Unfortunately, the photo is damaged, so I've broken it down into three parts which I individually enhanced with software below.
The nude model above seems to be sawing something. Shades of Muybridge.
The central figure seems more muscular when enlarged and clarified.
The nude model above has a bit of a pot belly and looks older than the other models.
The clothed man is holding a rag and has something on a shoulder strap I can't make out.
Is he dressed as a soldier? Or is he the helpful fluffer?
