Used Industrial Design Stamps - 4 Types Stored for a long time. There are scratches and stains. Please refrain from purchasing if you are concerned. "Industrial Design Stamps" are a type of definitive stamp issued in Japan. A total of 13 types were issued between October 1948 and November 1949. The Industrial Design Stamp series features workers who supported Japan's post-war recovery as the designs. Because the stamps were issued shortly after the war, the quality is somewhat lower compared to pre-war stamps, but the stamps have been highly regarded for their rich designs, unified themes, and overall cohesion."
