If I know the buyer I ask if they want my name on the quilt. If I am selling at a show or like I did in the past, at a local cafe, I prepared lables with printable fabric (the one with the glue on the back) with my name and year and iron them to the back of the wallhanging. If they don't want it they can peel it off. I always pin to the back of the quilt my bussiness card in case the buyer is interested on another one. I have had some calls from people keeping the card.
