A genuine vintage Japanese double-sided enamel advertising sign for Shibata Rubber Stamp (柴田ゴム), featuring the company’s distinctive white dove logo and bold blue background. The sign advertises “Hanko no Mise” (ハト印の店 / Dove Brand Stamp Shop), indicating an authorized retailer of Shibata rubber stamps. With its striking graphic design, vivid colors, and iconic dove illustration, this piece is an excellent example of mid-Showa Japanese commercial advertising. Both sides display the same design. The sign retains its original enamel finish and exhibits authentic age-related wear, including enamel loss, rust, scratches, edge wear, and mounting hole wear from decades of outdoor display. These characteristics enhance its originality and collectible appeal.
