This is a genuine vintage Japanese enamel advertising sign featuring 家庭染料「かも川染」 (Katei Senryō “Kamogawa Dye”), referring to household dye products. The bold blue lettering against a bright yellow background, with red accents, is characteristic of mid-20th century Showa-era commercial signage. The sign is double-sided and made of metal with an enamel finish. It shows significant aging, including rust, corrosion, stains, scratches, and areas of paint wear, giving it an authentic industrial and retro aesthetic highly valued by collectors. Such signs were typically used by local dye shops or retailers, making this a rare piece of Japanese advertising history. Its strong visual impact and aged patina make it ideal for display, interior decoration, or as part of a vintage collection. Please carefully review the photos for condition details.
