S2 Framed double sided, Japanese Post-War Enamel sign for a registered rice shop, (circa 1950s–1970s). Shiga Prefecture

A remarkable artifact of post-war Japanese commerce, this double-sided enamel sign certified an authorized rice dealer in Shiga Prefecture during the Showa period (1950s–1970s). Cast in heavy enamel-coated metal, the sign displays the characteristic "Showa Retro" aesthetic with a luminous yellow plum blossom motif anchoring bold indigo typography. Government-issued registration marks authenticated rice merchants across Japan, making this piece both a commercial emblem and official credential. The weathered surface preserves decades of street-side exposure, capturing the patina of mid-century Japanese retail culture. Measuring 33 by 45 centimeters, this dual-sided signage represents a vanished era of regulated commerce and traditional craftsmanship—an essential acquisition for collectors of vintage Japanese ephemera, Showa design, and industrial heritage.
