George Luks probably based this painting on the heavyweight championship fight held on July 4, 1910, between Jack Johnson and Jim Jeffries. The bout stirred up racial tensions in turn-of-the-century America, as Jeffries became the latest "Great White Hope" to try to reclaim the title from the African-American Johnson. Johnson won the match and race riots ensued in several American cities. Luks portrayed a dramatic moment in the fight-just after the African-American boxer has delivered a knockout punch to his opponent. Luks was a member of the Ashcan School, so named for the participating artists' depiction of gritty urban scenes. A keen fan of the sport, Luks gave himself boxing nicknames, including "Lame-em Luks," and died from injuries he suffered in a bar brawl in 1933.
