Just a quick look, there is record of a team named the Harlan Lion Tamers that played a game v. Lynch Bulldogs in Kentucky, May 1923. "Harlan Lion Tamers, lost to Lynch Bulldogs 12 to 2 in an exhibition game Saturday afternoon. The field was soaked in water and the players waded in mud up to their shoetops in an attempt to play. A home run with the bases full accounted for four runs gathered in one inning." Middlesboro Daily News, May 15, 1923. Here's an interesting African American Schools history in Harlan County, KY: http://nkaa.uky.edu/record.php?note_id=2797

I am not familiar with the area, or if these places are near Covington. Hope this is helpful. Good luck, and great looking broadside!
