Bests & Worsts Reviews from Amazon

The inside the book is fine, but there is a huge sticker on the back of the book that states: "Warning----To avoid danger of suffocation, keep away from babies and children. Do not use in cribs, beds, or play pens. This bag is not a toy" This sticker does not come off the cover of the book without tearing the book cover. Plus, this did not even come in a bag, so why is there a sticker like this even on it?
