This striking 12 centavos stamp from Peru (1905) features the Instituto Municipal de Higiene, finely engraved by the American Bank Note Company. The deep blue ornate frame enhances the architectural illustration, showcasing Peru’s early civic infrastructure. Your example bears a bold magenta overprint, applied during later postal rate adjustments—an attractive collectible variation sought after by specialists. The design also includes UPU markings, reflecting Peru’s integration into global postal reforms. A clean, sharply-printed issue that represents classic Peruvian engraving at its finest.
