This is a vintage brass plaque or sign, featuring the words "Kao Siang" rendered in a highly stylized, flowing script that resembles traditional Asian calligraphy. The plaque is cast in solid brass and has a warm, aged patina. There are small holes visible, indicating it was designed to be mounted, possibly as a nameplate, a decorative emblem, or a sign for a business or personal item. A ruler in some photos shows its length to be approximately 17-18 cm (around 7 inches). The design is elegant and unique, suggesting a custom or artisanal piece that would add a touch of vintage Asian charm to any space.
