An "Author Signature" refers to the unique way an author signs their name, often found on the title page of a book or in a personal correspondence. This signature can reflect the author's personality and style, making it a distinctive mark of their identity. In addition to personal signatures, some authors may also create a logo or symbol that represents their work, further enhancing their brand. These signatures and symbols can help readers easily identify their favorite authors, such as J.K. Rowling or Stephen King, and foster a connection between the author and their audience.
