Issued by the Soviet Union (USSR) in 1988, this commemorative stamp set celebrates the XV Winter Olympic Games held in Calgary, Canada. The series features dynamic illustrations of key winter sports disciplines, including biathlon, ski jumping, alpine skiing, cross-country skiing, and figure skating, capturing motion, athleticism, and Soviet sports artistry of the late Cold War era. Printed in rich multicolor tones, these stamps reflect both Olympic spirit and Soviet graphic design excellence. A classic thematic set ideal for Olympics, sports, and USSR philately collections, and highly suitable for exhibit pages or thematic compilations.
