Looking for Old Wayne County Fair Win Pictures

As part of an ongoing research project about the Wayne County Fair, located in Wooster, Ohio, it was discovered that we have had horse racing at the Fair since 1869.

I have asked a number of people when it became popular to hire a photographer and take a picture of the winning horse? When did the idea of a win picture come into vogue? When did a win picture photographer show up at the Wayne County Fair: 1920's, 1940's, 1960's? Nobody seems to remember, or know.

If you are, or were, a racehorse owner, driver, or trainer, please look at your collection of win photographs and see if you have a picture of a winning racehorse at the Wayne County Fair, and please send me the date of the picture, as i am looking for the oldest surviving photograph! If you have a win picture from the Wayne County Fair you would be willing to share (i would copy it to make a computer file out of it and return it to you), please contact me.
