This attractive Canadian semi-postal set was issued to commemorate the XXI Olympic Games held in Montreal in 1976, featuring dynamic artistic illustrations of three sporting events: gymnastics (10+5), soccer (20+5), and basketball (8+2). The “+” values represent charitable surcharges supporting Olympic-related initiatives, making these stamps historically significant both philatelically and socially. The expressive brush-style artwork and vibrant Olympic themes make the set particularly popular among Olympic topical collectors and sports philatelists. Well-preserved mint sets remain desirable additions to worldwide Olympic collections.
