This original Japanese enamel advertising sign (horo kanban) promotes Ormin (オーミン), a deworming medicine manufactured by Tomiyama Chemical (富山化学). The sign features the advertising phrase: * 「十二指腸虫の駆除に…」 (“For the elimination of hookworms…”) * 富山化学 (Tomiyama Chemical) Its bold black typography on a warm yellow background creates a striking visual impact typical of Japanese pharmaceutical advertising from the mid-20th century. The simple yet eye-catching design makes this piece highly desirable for collectors of vintage Japanese enamel signs, medical advertising, and Showa-era memorabilia. The front retains vibrant original colors despite decades of use, while the reverse exhibits heavy oxidation and weathering, providing an authentic vintage character. Rust, enamel loss, scratches, stains, and edge wear are consistent with long-term outdoor display.
