Anatomy of a Negro League photograph - help needed with year

These are awesome photos, and I have done a little work on the signs....

The Red Pegasus MobilOil sign suggests at earliest, 1930's, Happy Hollow Liquors & ButterNut Bread on right field fence suggest the repeal of Volstead Act, and acquisition by Interstate Bread Company (ButterNut/sign looks similar to Wonder). .

The most interesting is probably the Cook's Paint sign. Cook's Paint sponsored two AAU national championship basketball teams (1928-29), and owned a radio station in Kansas City (WHR?), 1930 - 50's.

The key, I feel, may be in the Frank L. Stephens Insurance sign. Though someone with access to a Kansas City Directory ca. 1930-40 for listings of Criterion Cleaners and Verdi Restaurant would probably be the most help. My guess is 1935-40.

Thanks Ty. Interesting info. I think you're on target. I'm still studying the Retrosheet MLB schedules from that period to see what games match up with the MLB games that show on the scoreboard (I wish there was Negro League game schedules and scores on Retrosheet!). I'm also still looking for some dated photos from the stadium that also show some of the advertisements for comparison.
