Obscure HOFer Cards?
 

I am looking for career-contemporary cards or memorabilia of some HOFers:

These are modern guys who I just cannot find anything for except photos:
Antonio Cervantes
Masao Ohba

These black fighters don't seem to have any cards, just photos:
Charley Burley
Cocoa Kid

These are pioneers:

Young Barney Aaron
Ben Brain
Harry Harris: I have a Police Gazette supplement but have not seen anything else
Henry Pearce
James Wharton (Young Molineaux)
