This is an exceptional piece of professional history: a vintage lapel pin from the Professional Business Institute in Minneapolis. This gold-toned badge features a striking textured gold center, proudly displaying a detailed Caduceus symbol—the staff entwined by two serpents and topped with wings—flanked by the letters 'M' and 'T'. This imagery elegantly combines the concepts of medical expertise and professional training. The central design is encircled by a crisp black enamel ring bearing the school's full title in clear gold lettering. Finished with a decorative scalloped edge, this pin is a sophisticated statement piece. It is perfect for collectors of medical memorabilia, alumni, or anyone who appreciates unique vintage vocational jewelry. It fastens securely with a standard pin stem and safety catch.
