Ella May Walker was an accomplished artist in several different styles and media types.

For her paintings she used a wide variety of material including oil, watercolour, gouache, pastel, tempera and charcoal. Ella was also a sculptor and taught evening classes in sculpture through the University of Alberta’s Faculty of Extension. Her subjects ranged from nature scenes, portraits and contemporary historic scenes to recreations of life in Edmonton’s early days.

Ella's historical artwork generally fell into two categories: capturing contemporary scenes and recreations of past scenes and events. Most of her contemporary work was the focus of her preservation efforts and many of her recreations were used to illustrate her book Fortress North.
