A woman in the center foreground turns to look over her left shoulder while behind her, two men in top hats observe this activity in a 1916 lithograph by the artist most famous for depicting this activity. In       another Eakins painting, a practitioner of this activity is shown almost naked except for a pair of blue-belted shorts and is raising his hand to a cheering crowd; that painting is titled Salutat. In one painting, a blue-shirted man in a tie is pointing towards the ground as spectators attempt to catch one man engaged in this activity who falls away from another participant who is wearing purple shorts. The artist of that painting also depicted a black man and a white man in green shorts engaged in this activity in 1909 at Sharkey's Athletic Club. For 10 points, identify this activity depicted in paintings like Eakins' Between Rounds, as well as in Both Members of This Club and Dempsey and Firpo by George Bellows.
