When I was growing up in Houston, there were photographers who would come through neighborhoods with Shetland ponies and a trunk full of cowboy costumes. They would take pictures of the kids in the neighborhood, and sell the prints to the parents. Most of the people I know from that period of time have at least one of these photographs. As I recall, the photographer used a large format camera. Does anyone know anything about these photographers? I've attached a copy of my "cowboy picture".
