This is an enamel sign for "Sumitomo Chemical Hoskaan with Urea". This sign is an advertisement for the chemical fertilizer "Hoskaan" manufactured and sold by Sumitomo Chemical (now Sumitomo Chemical). The words "Urea included" emphasize that this is a fertilizer to which urea, which contains nitrogen, has been added. After the war, Japan suffered from serious food shortages, and the demand for chemical fertilizers to improve agricultural efficiency increased sharply. The Showa era, when this sign was displayed, was a time when chemical fertilizers, which can be said to be a symbol of agricultural modernization, were widespread. Products such as "Hoskaan" were important materials for farmers to increase crop yields. The top of the sign features the diamond-shaped logo symbolizing the Sumitomo Group, appealing to its high reliability. This sign is a valuable item that symbolizes the development of agriculture and industry in Japan during the Showa era. It has a nostalgic atmosphere that evokes the scenes of the time when it was displayed in rural areas and stores. This sign is sure to be a special item for vintage fans and those interested in agricultural history. [Size] 60x17.4cm [Condition] Good vintage condition.
