Fun, engaging, educational book for kiddos to learn their ABC’s!

My son absolutely adores this book! We have to read it every night. It’s helping him learn his ABC’s and is fun for him because he loves all of the vehicles and pictures. Thank you for such a beautiful addition to our library at home, and for helping my son get ready for preschool!

First Rate
Format: Hardcover
My grandson (age 3) is just starting to recognize letters, and of course, he is all about planes, trains, and trucks. That's why I was glad to find this book! He really likes looking at each picture and telling me what it is. The pages are made with high quality, thick paper, so it should hold up well. The book says, "All illustrations for this book were hand-drawn in color pencil by Michael Kracht through inspiration from his children in heaven." And you can feel the love in every one.
