Author "trading cards". Author trading cards could list the biography of the author, as well as publication history. This would (hopefully) change over time, so your first publication would be your "rookie" card. They could either use a picture of the author, or (for the camera shy) cover art from the latest book.
On the website, have a place where you can type in your name, and it will tell you what Troll Wife would think you smell like. (My son's idea.)
