Go to the Columbus Historical Society. They probably have tons of yearbooks.
Similarly, I was able to obtain copies of 1919 - 1920 team photos of the Tonawanda, NY football team which later became the Kardex in 1920. They played one game (0-1-0), lost, and folded in 1921. Probably the most obscure NFL football team. There were numerous letters from the NFL Hall of Fame asking for ANY information on the team in their file. Well...I sat on the photocopies for 10 years and was able to identify some players on postcards that were listed on Ebay. It was one of my best finds ever. I'd try there...good luck!!
Here is a image to give you a little motivation. I think they are pretty cool.
