I don't think Diane Arbus used a  Brownie  Flash 6-20 at any point in her professional lifetime, but this looks like something she'd do.

The expressionless face, and the eyes barely visible through the sunglasses are  oddly disturbing.  The photographers shadow, the single piece of litter and the ongoing conversation with the pony fans to the right, are important elements in this lost photograph.

You've probably seen a million photographs of people in your life.  Most don't hold your interest unless they are photos of people you know.  This is not an uninteresting photograph.

There's no doubt that the air of mystery is heightened by the fact that you're seeing this photo for the first time . It's likely that all involved in this photograph are dead. If not, they're on Social Security. It was the only exposed frame on a roll of eight possiblities.

Who the hell is this guy ? Is he a truck driver ? Is he an official with the festivities in the background ? Is that his wife's shadow on his leg ?

What's he got strapped to his back ? Is there another pair of glasses in his shirt pocket or is that case for his sunglasses ? And what the hell is he so happy about ?

Is that a child or a dwarf over there by the pony ?  If you look behind the truck you'll see another dwarf-like figure standing next  to a mysterious man wearing a white shirt and dark tie.

Why was only one frame exposed that day ? Was the festival devoid of photo opportunities ? Did something bad happen ? Did the photographer succumb to overwhelming boredom ?

Well, none of these questions will ever be answered. The elements in this photograph came together for a fleeting moment. About 1/30 of a second. Then they moved on.

Kodak Verichrome film.

A witness to history.
