A signed piece of the original artwork from the book (I know I'm underselling this work, but it's for the greater good of the book), one of the special edition hand bound books, one of the paperback books, and of course the bookmark.
The special edition of Yesterday Brings Today: which is hand bound, with a hand cut silk screened hard cover. Each of these books will be signed and numbered from 2-21 of 21 (sorry, I'm holding onto 1 of 21) . . . plus everything above.
