A maker's mark is a unique symbol or signature used by artisans and manufacturers to identify their work. This mark can be found on various items, including ceramics, jewelry, and metalwork. It serves as a way to authenticate the piece and can provide information about the creator, the origin, and the date of production. These marks can vary in design and complexity, often reflecting the style of the maker or the era in which it was created. Collectors and historians use maker's marks to trace the history of an item and to assess its value and authenticity in the marketplace.
