🏭 Authentic Showa-Era Japanese Enamel Advertising Sign

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

📌 ITEM DETAILS

Step back into the golden age of Japanese industry with this 

rare, double-sided porcelain enamel sign from Oji Paper Co., 

Ltd. (王子製紙株式会社) — one of Japan's most iconic and 

historic paper manufacturers, founded in 1873.

The reverse side features the name "MIYUKI," referencing the 

legendary Ginza Miyuki Street (銀座みゆき通り) in Tokyo — a 

prestigious commercial boulevard synonymous with elegance and 

high-end retail culture in postwar Japan.

This sign was made to be seen from both directions, combining 

bold navy-blue kanji typography on a crisp white background, 

framed with a classic double-border design — a hallmark of 

quality Showa-era enamel signage.

🔵 Bold navy blue & white colorway

📐 Chamfered / clipped rectangular corners

✍️ Large vertical kanji: 王子製紙株式会社

🏷️ "MIYUKI" panel in Roman lettering at base
