Seamheads.com has a book review of "The Eastern Colored League" by David Lawrence and Dom Denaro. I haven’t read the book but it has an APBA twist to it.
The monograph project started with the authors wanting to improve upon the APBA set of 20 Greatest Negro League Teams by finding a methodology that would allow the Negro League compiled statistics, at least the fragment that has been compiled, to be converted into statistics that would have the Negro League APBA player cards play ‘realistically’ with MLB APBA cards.
The book is published by AJ Publishing and goes for a measly 9 bucks.
The review doesn’t say how they made the card set. Does the book? (Was it Staffa?)
I did find this

A set of cards based David Lawrence’s research. The cards are published by the APBA Journal.
that domain is parked.
