Thomann was a major force in cycling during the 1920s, sponsoring top riders including multiple Tour de France winner André Leducq. What sets this poster apart is its bold and unusual focus on the frame builder himself—a rarity in cycling advertising.

The artwork bursts with motion and energy. At its center, a welder—masked and glowing in shades of orange and red—joins bicycle tubes as golden sparks swirl outward. Five luminous bicycles orbit the central figure, suggesting both the craftsmanship and variety offered by the brand.

This poster has been archivally and professionally linen-backed.

Virtually all original vintage posters of this era were viewed as temporary advertising and were printed on fragile, thin paper. While expensive, linen backing is a conservation method used to mount, stabilize, preserve, and protect vintage posters so they can be displayed or framed without compromising value.
