Sketch for Opulent October

"Sketch for Opulent October" is a notable oil painting by Canadian artist Tom Thomson, created during the winter of 1914–15. The work was inspired by a sketch and study made possibly in Algonquin Park, capturing the lush, vibrant atmosphere of October. Measuring 115.1 × 102.0 cm, the painting reflects Thomson’s mastery of Post-impressionism, emphasizing bold colors and expressive forms. Painted on wood behind the Studio Building in Toronto, it marks a peak in Thomson’s brief but influential career. Acquired by the National Gallery of Canada in 1915, the piece remains a significant part of Canadian art history.
