Seller's Description Japanese Enamel Sign - "Salt Retailer/Telephone" (Showa Era) Salt retail sales during the Showa Era were conducted under the "Salt Monopoly System," which lasted from 1905 to 1997. Under this system, the government (Japan Tobacco and Salt Public Corporation, formerly Japan Tobacco) strictly controlled the production, import, distribution, and sale of salt, and retailers required a license. Existing signs, especially those with clear typography and official logos, are becoming increasingly rare. [Size] Left: 60x14cm Right: 30x30cm [Condition] In good vintage condition.
