I have nine sets of children's books. $10 for each set of 20. I will not separate the sets. Some books are in better shape than others. Some are brand new. Please let me know which picture you are interested in, (1, 2, 3, 4, 5, 6, 7....ect.). Set #1 has two extra books, because they are slim. A couple of other sets have books called Topsy Turvy, each of those are two books in one.
