Dempsey and Firpo

Dempsey and Firpo (sometimes referred to as Dempsey Through The Ropes) is a 1923–1924 oil canvas painting by George Bellows, depicting the September 14, 1923 boxing match between American Jack Dempsey and Argentine Luis Firpo. As time passed by it has become Bellows' most famous boxing painting. The work has been in the collection of the Whitney Museum of Art since the museum's opening in 1931.
The painting.
The painting depicts the dramatic moment when Firpo knocked Dempsey out of the ring, despite the fact that Dempsey was the eventual winner that night. Bellows gave himself a cameo as the balding man at the extreme left of the picture. The work is painting in the style of the Ashcan School movement.
In popular culture.
The painting is referenced in "The Simpsons" episode "The Homer They Fall" during a montage of Homer Simpson winning boxing matches, where he and Moe Syzlak taking the poses of respectively Firpo and the referee.
The painting also appears briefly overhead a fireplace in the third episode of The People V. O.J. Simpson.
The fight, that is the subject of the work, is also cited by Mickey Goldmill in the movie "Rocky" during his visit with Rocky in which he attempts to convince Rocky to retain him as his manager.
