This 1979 Swedish commemorative stamp marks the 100th anniversary of the historic Sundsvall Strike of 1879, one of Sweden’s earliest major labor movements. The design depicts industrial workers in the foreground with a sawmill and smokestack behind them, symbolizing the timber industry that dominated the region. Rendered in a bold brown and red palette, the engraving-style artwork reflects the strength and resilience of the labor movement. A significant issue for collectors of labor history, industrial heritage, and Scandinavian social history themes. The inscription “SUNDSVALLSSTREJKEN 100 ÅR 1979” clearly identifies its commemorative purpose.
