Nothing from the Negro League Center in Cleveland yet. I wrote them an email and attached the picture but is was flagged as undelivered address. I did find this on Wikipedia so there cant be many as stated above.
"The Cleveland Tigers were a Negro league baseball team in the Negro National League, based in Cleveland, Ohio, in 1928. In their only season, they finished in seventh place with a 20-59 record."
So only one season!
