The Jolly Postman or Other People's Letters
, Janet Ahlberg
Loved this book as a child and couldn't wait to read it to my little boy. He's now 6 and still enjoys reading it with me. The story and illustrations are lovely. Also, it's exciting to see what the Jolly Postman has to deliver to the various characters in the book, with little slots for you to get them out to see what they've got. You won't be disappointed.
