Received a private reply that it was Northville Downs and Carl Putnam (didn't say if it was Sr., (died 1976) or Jr.
Hate to burst the Alessi/Mayood bubble, however I've received replies from multiple Mich folks that this is Carl Putnam Jr., and the track is Northville (note the opening in the fence, which is where the old ramp used to be located and where the horses crossed Seven Mile and Sheldon Roads from the old holding barns.
I don't have any photo's of Carl, however as many times as I've seen him close up and the name brought the vivid recollection of his face, the photo is definitely he.
Many thanks for all the replies and everybody's efforts to help ID this photo.
