The NNL split the season into two halves. Kansas City won the first half, Chicago won the second half. The teams met at the end of the season in a best-of-9 playoff series to determine the Champion.
The Negro National League and the Eastern Colored League faced each other in a Colored World Series at the end of the season to determine an overall champion.
I sincerely appreciate the research work, and the information being shared. It is important and interesting history.
