Well, this is supposed to be a children’s book, but I can imagine very many adults ( including me) spending hours getting lost in its eclectic selection of facts and figures. Cartoons are very busy and crowded, but that might just be due to the fact that I’m only looking at it on a small screen! The inquisitive child will love this book for adults might spend a lot of time checking the facts.. although as we all know: the more unlikely it seems, the more likely it is to be true..Good stuff..
