Issued in 1967, this Belgian stamp celebrates the nation’s historic flax industry — a vital part of its textile heritage. The design features a stylized depiction of blue flax flowers growing from an industrial loom or spindle, symbolizing the union of nature and technology. The clean modernist composition contrasts delicate botanical forms with industrial geometry, reflecting postwar optimism and innovation in Belgian craftsmanship. Inscribed Vlasnijverheid / Industrie Linère (“Flax Industry”) and denominated 6F, this issue belongs to Belgium’s “Industry” series that highlights key national economic sectors.
