#The "Kankan Kankan" train is coming! #What kind of vehicle is it? #The railroad crossing goes "Kankan Kaaan"! This is a set of 3 books. My son, who is currently 3 years old, enjoyed reading them. I think they are suitable for children aged 1-2. They have been used very little. The covers were removed and stored separately, so the books themselves are in good condition.
