Irene McCaugherty's subject matter was drawn from the interest she and her husband shared in rodeos and livestock. It also comes from stories old-timers told her about their experiences from settlement and rough rural life; painting was her way of recording these stories. Her pieces were a trademark size of 50 centimetres, because she painted landscape as seen through her truck windshield. Not only did she enjoy painting, she was also a photographer and writer. Many rural newspapers published her writing regularly. She worked with all three arts from 1950 until the end of her life, in 1996.
