Great books but the “That’s not my plane” book has one page where the propellers are rough but they are shiny so you have to skip the page or you will be teaching your kids something that’s not visually correct. Not sure how many of these are around but as there are only few pages you would expect such a basic to be correct. I have several of these and all are perfect. This one was first from eBay so quite disappointed. Otherwise the other pages are great and like that they are different from the animal ones.
