Can a calligraphy work be stamped without signature?

No A complete calligraphy work consists of three parts: calligraphy content, inscription and seal, and the calligraphy content and inscription content also have corresponding requirements. The content of the inscription can be determined according to the scale of the calligraphy works. Simply put, only the name of the writer can be stamped, and the time, place and name can be stamped. A more complete description of the source, time, place and name of the calligraphy content can be made and stamped. Therefore, it is impossible to stamp a calligraphy work without an inscription.
