Great lineup this year and John Maggard did the poster! (I assume he is signing the poster at BBTB?)
Other illustrators include Loren Long (who is on a panel), C.F. Payne, Will Hillenbrand, Christina Wald, Carol Tyler, and many others. There are also a lot of great authors so check it out!
Check the link for the list of books, authors and illustrators. It is a great event and gets bigger every year.
