This is a book about an anamorphic bunny who says goodnight to numerous things. It is often recited in a soothing voice. Written by Margaret Wise Brown, the book is aimed at readers below 1 year old.
While the book has endured for 75 years, how it survives for the regular 1 or 200 years is the question. I this day and age, the book still endures as a popular, relevant story with lots of drawings and vocabulary to keep young readers interested.
