Mount Assiniboine, c 1943, is a 13 x 20 inch watercolour on paper painting by Polish Canadian artist, Rafal Malczewski. Malczewski’s work, although difficult to categorize, is recognizable by its modernist approach with some of his work showing expressionist influence, blending traditional landscape painting with contemporary techniques. 

Mount Assiniboine, often called the "Matterhorn of North America," is a striking peak in the Canadian Rockies that became an inspiration to many Canadian artists. The mountain represents the untamed beauty of the Canadian wilderness, inspiring artists to capture its grandeur. Malczewski’s work is one of many examples of how artists were redefining landscape subjects in the mid-20th century. His use of a vibrant colour palette brings his landscapes to life, creating striking visual contrasts between land and sky, mountains and plains. Malczewski's painting captures the mountain's majesty with a delicate balance between detail and abstraction.
