B&W photo of Australian champion steeplechaser, Mosstrooper, with his owner and trainer, Robert Gustavius "Gus" Powell, in the saddle. Gus is wearing a pale hat and a light-coloured suit and is carrying a whip. He has a pipe in his mouth. He was a personal friend of William Hermon Snr. The photo may have been taken in Lysterfield. There is a large cleared area with what appear to be low hills in the background.
