Daniel Jennewein is the debut illustrator of Is Your Buffalo Ready for Kindergarten? written by Audrey Vernick (Balzer+Bray/HarperCollins, 2011). From the promotional copy:
Your buffalo is growing up. He plays with friends. He shares his toys. He’s smart! But is he ready for kindergarten? (And is kindergarten ready for him?)
