A genuine Japanese vintage double-sided enamel advertising sign for AKIMAI Rubber Shoes, featuring two historic trademarks and an elegant pre-war to early Showa design. The sign displays: * 責任印 (Guaranteed Mark) with the traditional AKIMAI emblem. * サクラ印 (Sakura Mark) with the distinctive cherry blossom logo and the English inscription “AKIMAI TRADE MARK”. * The advertising slogan: 「昔から強い」 “Strong since long ago.” * Bottom inscription: 「神戸 秋毎ゴム特約店」 “Authorized Dealer of Kobe Akimai Rubber Shoes.” The combination of Japanese calligraphy, English typography, and the cherry blossom emblem gives this sign exceptional visual appeal and historical significance. The vivid cobalt blue background contrasts beautifully with the red and white logos, a characteristic feature of Japanese commercial enamel signs from the early Showa era. This sign is double-sided, and both sides retain their original enamel finish with a glossy surface. The sign shows authentic signs of age, including edge wear, scratches, small enamel losses, and rust around some mounting holes, enhancing its genuine vintage character. This is an original period sign and not a reproduction.
