Autograph, autograph is signed by the parties one by one. Some parties sign their names one by one on the signature page before binding their works, and then bind and list them. Some are signed by the parties one by one after the binding is completed, and then put on the market. There are plenty of signatures at the sales activity site. Autographing is a hard and time-consuming job, so most of them are below 2000 copies.
