What a fun book! The train unfolds and creates an illusion of the real thing. Each train car has flap you can lift and there are questions about what you see.
Abrams Appleseed sent me a copy to review (thank you). It has been published so you can get a copy now.
This board book is great but you'll need to supervise those small hands so they don't damage it. The questions are not hard and the answers are easy to find. A child will want to play with their train several times. You can help them learn to see the right thing in the illustration and then they are off!
