Picnic Man

From an old family photo.  Subject/date unknown.

Picture I know nothing about, maybe 1920s.  A bright sunny day in a clearing with trees in the background, looks like a line of trees with another clearing, field, or roadway behind.  A group of people wearing various hats is gathered under the trees, and a child in white sits near an old car parked under the trees.
A man near the edge of the clearing is holding a partly-folded cloth that reflects the sun.
In the foreground, facing sideways/diagonal to the camera, stands a man in a white suit and dark hat.  His entire face is in shadow and his hands are clenched loosely at his sides.  He wears shiny, dark leather shoes.  He stands on thin grass in sandy soil, in a well-trodden part of the clearing.  He's wearing a tie, and something soft is wadded in the pocket of his suit jacket.  A bandana or tobacco pouch, maybe.

My question for the world around me:  Is there something you're not telling me?
