My favorite series for children has a wonderful new collection: Mo Willems’ Pigeon and Pals: Complete Cartoon Collection Volumes 1 & 2. Emmy Award winner and Sesame Street veteran Mo Willems is the author/illustrator of the delightful book series about the irrepressible pigeon who is determined to drive a bus and eat a hot dog, as well as the Knuffle Bunny series and more. This collection includes six stories on two DVDs and extra features with Willems visiting a school and a Spanish version of “Knuffle Bunny: A Cautionary Tale.” I have one copy to give away. Send me an email at email@example.com with “Pigeon” in the subject line and tell me your favorite picture book. Don’t forget your address! (US addresses only.) I’ll pick one winner at random on May 2.
