lron- and steelmaking motives on stampsand postcards can stimulate the interest in historical metallurgy. In the present instance, such illustrative documentation brings about the commemorationof the 140th anniversary of blast furnace ironmaking in Japan. KEYWORDS:historical metallurgy; early blast furnace works in Japan.
