This French stamp, issued in 1937, depicts a group of coal miners returning from their arduous labor, symbolizing the strength and dignity of the working class. Designed by Henri Cheffer, the detailed engraving shows miners carrying tools, with an industrial mining structure and smokestacks in the background. The stamp, denominated at 2 Francs 15 Centimes, was part of a series celebrating workers and industry during the interwar period. It reflects France’s emphasis on honoring labor and industrial progress. A classic piece of French philately, it is highly valued by collectors for its strong socialist-realist style and historical significance.
