Negro baseball cards would be included in baseball. We'd add them as their own sets instead of adding them as a separate sport. Please let us know if we are missing particular sets of interest for those.
I changed this to a particular sport. We have suggestions for some other sports but breaking it out into boxing only helps us know which sports people want us to focus on next.
