There aren't a whole lot of 19th century and early 20th century cards for collectors of athletes of African origins. Boxing probably offers the most. Afro-Canadian George Godfrey appeared in N174:

Also appearing was Afro-Australian Peter Jackson, who also had several cards in the Newsboy series. Godfrey and Jackson were joined by Afro-Caribbean Barbados Joe Walcott and Afro-Canadian George Dixon in the N310 Mayo issue. N266 Red Cross has Godfrey, Jackson and Dixon. N332 S.F. Hess has Godfrey and Jackson. N269 Red Cross has African-American boxer Harry Woodson. I suppose Woodson would be the first African-
American boxer with a card.
