A.J. Casson often sketched in the Lake Rosseau and Lake Joseph regions of Muskoka throughout the 1920s. At this point, the young yet undeniably accomplished artist had been painting with members of the Group of Seven since he began his apprenticeship under Group member Franklin Carmichael at the commercial art firm Rous & Mann Ltd. in 1919. It was the same year that this lovely, gently crepuscular sketch was produced, however, that he would be formally invited by Carmichael to fill the vacancy left by the departed Frank Johnston, becoming a full member of the Group. Although surrounded by the imposing presences of these ground-breaking artists, Casson very successfully maintained his own unique voice, producing works such as this one, imbued with both a poetic sensibility and deeply felt humanity.
